I feel fortunate that most of my commute is over quiet country roads with minimal traffic. I get regular sightings of wildlife from the usual bunny rabbits and squirrels to the occasional deer or great blue heron. I do have a part of my trip just before I arrive at the office where I climb a 150 foot hill over 3/4 mile of busy road. So even in cool weather I arrive at the office sweaty. A quick change of clothes takes care of that, mostly. The fact that work at an environmental office means any residual is humored. And I have a "special" sheltered place to park my cycle.
I have a recumbent because my rear end can no longer take the pressure of an eight mile ride on a standard bicycle, and a tricycle because I am too old to master the balance on a recumbent bicycle without serious injury. (See my brother peteralway recent entries for an idea of what I mean.) The tricycle I have is the tall fat guy version (Magnum) of the Road Runner from Lightfoot Cycles. It was one of those things that I could only afford because of an inheritance, but I am glad I got it. It has been a lot of fun and is really the only serious exercise I get. I must admit it is my one "healthy lifestyle choice" that I am able to actually sustain.
