I recently took a roadtrip about 1500 miles to visit some family. On the way to/back we wanted to stop and check out some cities the kids wanted to visit and it's amazing the anxiety I had every time we drove into a large urban area, all about traffic and parking. Most of the time, like you said, there was no place to park so I drove around and around with hundreds of other people while the kids complained about not being able to get out. It's like you said, if you knew where you were going you may be able to map it out, which also gives me anxiety (ok kids, we need to leave now to get to the next parking spot). I don't know, each time I was glad to leave.
