I just added Uncle P's antiques to the NPC store database. I wanted to make it available only if you'd opened the beach, but there doesn't seem to be code to support that, yet.
The Desert zones and stores are available if you have one of three Quest items in inventory:
- bitchin' Meat car
- Desert Bus pass
- pumpkin carriage
That's it; they are all quest items, and no more untinkering your Meat car, so simple presence of one or another suffices.
Things you can do if and only if you have such access:
- Shore trips
- Shop at Uncle P's and the Gno-mart
- Adventure South of the Border and in the Thugnderdome
- Set the Annoy-o-tron
