Here are a few random things I have learned while I have been living in Boulder...

- keep right instead of left
- no the toilet is not blocked, it is supposed to be full to the top with water
- if asked "are you from Australia?" reply with "are you from Canada?"
- no more than 2 per lane in public swim lanes (not an actual rule, just somthing they seem to do)
- squirrels are cute
- squirrels have rabies (not sure if this is true)
- fake tans and boob jobs are the norm
- always order the small
- it only ever rains in the evening
- you need to own a dog
- if you can see over the dash of your car, its to small
- watch out for praire dogs - they are everywhere
- make sure you are armed if you plan on visiting the towns in the mountains

Oh and if you are putting on a wetsuit, make sure you are putting your left leg in the left leg of the wetsuit otherwise you will have trouble when you go to put your right leg in.
