Well, for you clones, Now I'm done.
The best pilgrim's bounty guide I found was
The OverAchiever's at WoW Insider. Here's the bit for finding Horde tables for the Pilgrim's Peril achievement.
Southeast of the main gates (just south of the path to the Undercity/Grom'Gol zeppelin tower). Alliance players will not flagged here on PvE servers.
In the Ruins of Lordaeron courtyard immediately inside the main entrance to the city. Despite not being located far into the complex, this is the nastiest area for Alliance to reach, as there's steady Horde traffic from both the zeppelins and Silvermoon teleport, and the entrance to the Ruins is an unfortunate choke point. Don't go at server high time.
Directly below the western elevators [note that that isn't the western mesa, but the elevator on the western side of the city -- Jal]. Despite appearing to be outside of the city, the feast area is still within it and will get Alliance players flagged.
City South of the city's main gates. Alliance players will not get flagged here on PvE servers.
Silvermoon was easy to aggro if you came in the back to the table and not from the path. Stay on the path.
Remember that you only have to sit down at the tables for Pilgrim's peril!! I ate five of each item in Orgrimmar and Thunder Bluff. Luckily the only curious Horde in Thunder Bluff, where you do, sure enough, get flagged for PvP when you approach the table, were all well below 70. Kinda wanted the three obviously watching to give me their best shot, but no luck.
For Turkey Lurkey, I got everyone but the Dwarf, Orc, and Troll rogue turke-i-fied without trouble, but had to get the dwarf from a level one near the flight master in IF and the orc from someone who was politely dancing outside of Stormwind. Several people are putting n00b rolled PCs for easy featherings within shot of the Alliance city tables.
For the troll, I finally gave up waiting for a hand-out and went to the troll starting area, remembering Malone's advice about not going to the barrel (though I did waste some time hovering over Dalaran) and heading to the tree. Remember that the troll rogue starting area isn't on the mainland but on the small island to the east. Picture of me feathering a n00b troll rogue in the starting area below (check minimap).
And then, to find Talon King Ikiss. Reports seem to suggest you can gank him whenever you want, not just during the Pilgrim's Bounty event (which ends tomorrow), so I saved this until last.
Might be useful to recall that you can port to the Outlands now: How to get to the Outlands portal from any Major city in World of Warcraft | eHow.com
1. In Stormwind coming from main gates turn left out of trade district cross bridge go through tunnel to mage corner. Climb the ramp going into the mage tower and its right inside the door.
2. Darnassus go to the middle bridge and straight ahead in the Temple of the Moon
3. Iron Forge[sic] from the front gate turn left its in the Mystic ward in the hall of mysteries
4. Exodar the center of the city take the middle ramp it is in the Vault of Lights
Then you'll want the Sethekk Halls Map from WoWpedia. And don't forget to put on your pilgrim gear (hat and outfit) before waxing Ilkiss. Yes, I forgot too the first time. If you do forget, exit (a tedious process) and right-click your portrait to reset all instances. That'll bring him back to life. I was able to stealth in without incident and all but walk on top of the patrolling mobs. I did accidentally aggro once, and lots of Avian Rippers had heck to pay.
For Turkey Lurky, I had some trouble getting 40 turkeys 30 seconds apart until I went to Tirisfal Glades. And note that the Turkey Caller does not give a legit wild turkey. The turkey it summons is, however, killable (and lootable) for other quests.
And man, does travel form made hunting turkeys a heck of a lot easier. Run, smack once, loot, run some more.
Worth it? I don't know. Probably not. The pet is cute. I didn't have any title to date, so I figured I'd go for this one. It was fun-ish, and without any clear direction for WotLK until Cata really busts out, it was something to help get me used to playing again.
And here's some requisite video of the pet reward getting a little too close to the cooking fire. Start about 30 seconds in.
