My blonde hair probably contributed to our racial profiling and most people thought we were Swiss.Sure, it was slightly annoying to be pulled over all the time, (at least it wasn't for speeding) but it's their country and they make the rules.

I know you weren't just saying it's not quite the same, that's all.I have some chart on my home page here, activity levels, there is no base line I found, have no idea what that is or is suppose to represent.
