Buffalo T-Shirts and Affiliate Marketing

I just started reading about affiliate marketing to determine if this is an avenue that makes sense for BfloTees, Buffalo T-shirts and Design.
My initial, and perhaps, ignorant questions are:
Is there an affiliate marketing program that can group other Buffalo, NY stores together?
If so, can I review/select who I want to affiliate with? I assume so, but gotta ask. Obviously I wouldnt want to affiliate with an auto tire retailer. Unless I come up with a shirt or something that targets that customer base. Which would open the network to a whole other set of affiliates. But I digress.
Initial types of businesses to affiliate with:
gifts/souvenirs retailers
clothing stores
Buffalo hotels
tourism board
Buffalo arts, entertainment and recreational entities,
buffalo bloggers.

Im going to follow therandomeforest and his quest for affiliate marketing dominance. He's got a head start on me as far as research, but that's good-he's done all the legwork. Just sign up and follow him, ask questions and learn something new. Your mom would be proud.
