Crazy or Free Spirited

So I went to a large city park with the family and we had a great time. This park did attract all sorts and I had to laugh and wonder. First we walk by a group of guys doing organized martial arts in the field, then right next to them is a guy doing his own kind of martial arts, maybe hoping someone would notice him. Then just as we are already feeling entertained we round a corner and see that a group of people are having their own renaissance fair and no one else got the notice. Yep they're all dressed up in period costumes, but wait they have some how thrown star wars into the mix and are "jousting" with plastic laser swords and bats?!? Okay so what is the deal, I wonder if they look at me and think I'm the strange one. Then I thought maybe it would be liberating to walk around a park wearing a toga or something, I don't know. So what do you think are they crazy, socially inept or are they just so confident with them selves that the typical social boundaries mean nothing? What do you think?
