and I'm a backpack girl. I just bought a new slightly larger one so I can carry my heavier clothes in the winter. As for commuting on busy streets:
I've done it here and Beta is right (although I would've used the word "assertive" LOL) Anyway, you are entitled to 3 feet of lane as a biker. I try to be very aware of cars here and try not to upset them but on the occassions when I've had to ride on busy streets with no bike lane, I take my 3 feet and hold my line. That way the cars Know I'm there and that I'm not afraid. As a rule on left hand turns I do take the turn lane IF I can get across the traffic. I will stay to the right of the lane or close to the lane line, (whichever is easier to visual) so cars behind me that are turning have the room to pass me as we both make the turn. It tends to not upset the drivers so much. I'll also crowd the crosswalk lines so the cars can get far enough forward in the lane to trip the signal. It seems to pacify the drivers about having a cyclist in the turn lane. On the rare occassion (I don't think I'm spelling that word right) I can't get into the left turn lane, yes, I'll pull up onto the sidewalk and use it to cross the street. There are times in the winter when I wonder why I'm doing this - but then I get on the bike and start commuting, and it all comes back to me! Enjoy your commute!! and Let us know how it goes!!
and Beta: congrats on your commuting. I'm glad to hear you were able to work a route out! Isn't commuting awesome!!!???
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
