That's probably about right, the only time I've witnessed trouble is with younger travelers. I once found myself in the middle of a travelers event once, just looked like a market in a field. Until I realized something was a little odd about what was being sold... A lot of ornate china stalls (plates etc), brightly colored women's clothing stalls etc and just a general feeling of 'yesteryear'. Wasn't until I was right in the middle of it did I realize what it was. No trouble or threatening atmosphere though, no problems.
