Rockymtn_girl's signature line "Bicycling is a big part of the future. It has to be. There's something wrong with a society that drives a car to workout in a gym." - Bill Nye, the Science Guy, is one of the wonders of the modern world.
At my office building, we have a gym in the basement. I have even seen military people in their "war suits" and carrying gym bags get on the elevator on the first floor and press "B" to go work out!
How about the cyclists who put their bike on the rack, drive 5 miles to the trail, ride 10 miles, put the bike back on the rack, and drive home, all on suburban roads with bike lanes!
Of course, both are better than sitting on your fat bum, clicking through the channel and eating Nachos.
