I've recently set up wifi in my coffee shop on the southeast side of Tucson, and I'm trying to figure out how to get the word out so people can start using it. Your post mentioned that you had done a search to find out who has wifi in Tucson. Can you tell me what keywords you used in your search so I can find some of the sites that I can register with? (My search on "Wifi, Tucson" got me your post plus about 7,000 others.) I appreciate any tips you can offer. Thanks.
