today i commuted to work today with my bike. it feels great, i had a good ride here, and the traffic was nice and even at the big intersection i was concerned about, i caught it green and went on through while traffic waited for me. i made the mistake of wearing a cotton tshirt, stupid i know and i need to find another backpack to use. mine is to big and bulky. nyone know of a smaller, lightweight, streamlined backpack i can fit my shoes, clothes, and maybe a few grocery items in? i did some research in the commuting forum over them weekend, yall are TONS of help. what is normal and second nature, is stuff us newbs have never thought about so thanks for sharing your insights and experience to help newcomers commute safely, and effeciently.
