I was the model manager for Pornication a few years back and I found boys everywhere I went: the gym, the grocery store, the mall....as Jasun said, there are hot guys everywhere in this world. Keep some cards with you and hand them out. Flyering at Universities is a GREAT way to get fresh, hot and EAGER (usually curious) talent...just be sure to get administration approval before posting...and try not to post anything too explicit. Otherwise you could be looking at some fines.
