I think the Southern suburbs are pretty good to bike commute on. There are nice wide bike lanes along the side of the main arterial roads. Once you know the area, the trails inside the community and open space areas can be used cut alot of distance off of the road routes. From my home I can hit the C-470 trail for east and west access. I can take the platte river trail to downtown or catch the light rail as well. I am also within riding distance of Waterton and Deer Creek Canyons. My commute is 15 miles to Inverness Depending on my mood I have the choice to ride streets or mups. I have noticed several other commuters lately as well. There are enough people riding to the grocery store that they recently installed a bike rack there. I routinley ride to the library and run quite a few errands on my bike. Weekends are for sure the busiest times for bicycle traffic but I still see other riders every day of the week.
