I'm always paraniod to where I'm parking my bike. I pretty much never take it anywhere that I can keep my eyes on it or park it somewhere safe (like in a friend's garage). I don't want some punk stealing it or kicking it over. I don't even drive it to school since I don't know where to park it.
Suggestions on where and how to park a bike? E.g. On the side of a street? In a parking lot? End of streets? With other bikes?
Where some safe places to park bikes and not so safe places? E.g. Downtown? Movie theather? Mall?
