+1 on taking the lane. If I am on a really wide street that is only one lane (like a neighborhood), where people aren't driving fast, then I will get over to the right and share the road. But, if there is a lane for people to pass, of the road is too narrow for someone to pass you...then take the lane. This means riding in the middle of the lane. If you ride just right of center---it invites cars to pass you in the same lane, which they often can't do safely. This means that you are likely to get brushed/hit etc. etc.

Also, at stop lights, if you are a few cars back at a light, don't ride up in between or next to cars to get in the front (one of my pet peeves of cyclists!!).... this is annoying to cars, gives the rest of us a bad name, and also puts you in a dangerous place----- not only were you passing cars when they weren't looking for you, but you are putting yourself in a position where they have to pass you again after the light goes green.

Good luck and enjoy your bike!!!
