Hello there!
Sorry for not replying: yes, i've managed to go to Hot Lead for a few hours, although there was a massive crowd and i just met a few people. Being an outsider, and whithout enough time to play games, that was the best i could do.
I'm rather happy of my experience there: the place was heartwarming, and a lot of nice people talked with me. Too bad that i didn't have cash and the ATMs didn't like my credit card... but i still have a nice lead mountain brought with me from Italy, so i'll be allright.
Thanks again for your help, LAFers! it was a pleasure to meet some of you!
