I hope this is the start of something great. When I lived in Vancouver BC I was in a weekly walking group which used regular transit all over the metropolitan area to connect to parks and trails. Some of those were long rides, since route stops were involved, so the amount of time to walk wasn't always ideal. Doing all of it with friends still made for a fun day's experience, however, and it certainly opened doors to the outdoors for many who didn't own cars or no longer wanted to drive to those areas for reasons ranging from physical to environmental.
