Some guy I met at the gas station the other day was 16 with a 4 door jk and found out I was 21 and kept saying, "come on, buy me beer, we're jeep brothers!" Idiot..
I generally wave at anyone and everyone but most either blatantly ignore me or give me some discussed look. I've been trying to wave at every jeep I see you're the first to return it so far. But out in the Macedonia backroads, I can wave at anyone and bet money they'll return the favor..
