Try calling one of the bigger beer stores - Think Marty's, Blanchard's, Martignetti's....
You need to know in advance what kegs you're gonna try to attach - a keg of Bud uses a different tap than a cornelius keg of a craft beer.
Worst case, Google "homebrew club" in the area you're thinking of and start begging... :)
Cornelius (Corney) Kegs are really only used by home brewers nowadays. There are only a few different sankeys (device used to attach taps to kegs) used in today's kegs. American, European, German and English/Irish . And most imports are standardizing to the American sankey, thanks to in-bev. Most large stores should have a rental.
