Once you have bikes, walkers/joggers, surrey bikes, it can already be pretty busy.
The golf cart guy who passed me was very nice - it was funny, because I was walking later than normal, and I was fine until he came along. I stepped off the pavement, tripped, twisted my ankle slightly (not enough to really get hurt) and he stopped and asked if I was okay (not that he saw me hurt myself, he was just wondering why I was out there at night I guess!)
