Wimmens on bikes = Yay! And I understand the potential "squishy" commutes .. been car-free about 8 years or so myself (by choice) - and in bad weather - but I also have the option of riding a bus to work that is a big 12-15 plus minute ride to work. While I prefer to have my freedom - I also like to be safe - so in icey, very snowy weather I opt for a bus. Especially when it comes to "drive-time" - and I don't feel bad about it either. Cause when I get home I'm usually back on the bike to go shopping, just riding etc. I would prefer to feel safe than sorry.
And, if you haven't investigated - there's a few different forums that are for commuters, Living Car Free, etc - and more. Hit Foo for a funky ride and you'll also find many of us are also on the other forums they offer here.
Welcome!
