Thanks for the responses so far! Lots of food for thought which I appreciate.
My wife and I grew up in Florida and lived there until about 3 years ago. Before kids I was quite the mountain biker and occasional road biker, but my cycling recently (over the last 4+ years) has been limited to using the Gary Fisher to tow the kids around in the Burley... Looking forward to getting back into it!!
In the year-round heat and humidity of FL, I never considered commuting by bike, but the nice thing about CO is that even in the summer the mornings are generally cool and dry. Add in the fact that I work in a school and am usually at work by 7AM and my morning commute shouldn't be too bad.
