Which station are you riding from? I live in castle rock used to drive half my commute. I used to park at the mineral station and ride to evens on the platte. That parking lot is filled by 7:00AM, so I started parking in the lot for the nature center. After a couple of months I got a nasty note left on my car saying the lot was strickly for park users and not bike commuters. I then moved out to the trailhead/dogpark lot at 470 and Santa Fe until I almost had my car locked in one night. That's when I got bold and started parking on the south side of chatfield. My ride grew from 7 miles to 10 to 18 each way, and blossumed from two or three times week in the summer to full on, daily, year round commuting. The S. Platte Greenway is a great MUP as long as you keep your speed in check and try not to associate yourself with the guys that are using it to train. Those guys kill people on that MUP.....literally.
