You should go. The conventions are always a good time and while there is alot of drinking and partying, there is ALOT of business. Guys will ask you if you are an industry model, but they don't harrass, at least I've never been harrassed. Everyone is cool and down to Earth. The conventions are about making contacts and building business relationships so that we all can make more money!
I'll be in LA on Friday if you want to meet up.
