Some of this commuting stuff is learn by doing. I was a fair weather commuter for many years without the luxury of the internet. I have definitely learned a lot since joining this forum and for the past 2-3 years have been a year round commuter.

For quick jaunts around with not a lot of weight a backpack maybe fine. However, if you want to start carrying bulky and/or heavier items then a rack is the way to go. For hauling items like groceries get some panniers and/or basket(s).

Right now I have a milk crate attached to my rack so I can put my backpack in it when I carry it; or I can throw a couple bags of groceries in it when I go shopping.

Anyways its always great to see more and more commuters so keep it up .
