For the past few mornings, I've been working in a 45-minute walk before I head into work. I've dubbed this time "Big Dog Hour" because all my neighbors with dogs 100 pounds or more seem to be out and about.

But I've noticed a different trend as well. I've seen well-suited cyclists pedaling by in what feels like droves. The weather is not very pleasant in Phoenix right now. It's feels about 90 degrees at 5 a.m. and with the pending monsoon season, humidity is also pretty high. My conclusion is that these cyclists are trying to avoid the gas pump. Here gas is about $4.20 a gallon. In addition to the cost-saving benefits, they're obviously getting in a pretty good work out.

I would love to jump on the cycling bandwagon but given my 40-mile daily commute and the ridiculous temps, not sure if this is for me. Would you bike to work? What would be the incentive for you to jump on a bicycle?
