Lots of people on RIU meet up, a bunch of guys in the SoCal thread meet up, and they're having that BBQ on Saturday in NorCal...I think it's like all things, there are good people and bad people on herer, and it's up to you to make the judgement as to whether or not you feel comfortable meeting that person...
That being said, I don't think and of the 19 y/o girls on here should go around meeting guys on RIU by themselves...
