I alughed at the "wearing shorts when it's cold." That's defintiely true here in Colorado. people wear shorts when it's in the 30s or 40s, but in all fairness, when the sun is shining, it feels warm because the sun is so strong in our high altitude and dry air.
Now conversely, how to spot a Euro tourist:
1. backpack style
2. colored socks with white sneakers
3. jeans style
