I had some very close calls riding in some very ghetto areas today. It's a whole different world. When 50% of your attention is constantly on the broken glass on the road and 50% is on not getting nailed by someone blowing a stop sign or talking on a cell phone, well, its not a very fun ride. Almost got run into a curb, parked car, or moving car about 5 times as drivers decided that the far right of the street (parking space or bike lane) was the fast lane to get around traffic. Also saw a pretty crazy hit-and-run.
I'm definitely with ostro on his choice though. The people who are just about to blow a stop sign and then stop at the last second after making me do some sort of life-threatening skid-stop to avoid them then wave me through just... argh. Drive the way you would normally, and then at least I would know what the hell you are going to do!
Sorry, put in a lot of miles today on bad roads and in questionable areas, and had to deal with a lot of crap. Hope no one minds the rant.
