I've been riding Shank's mare lately and discovering new routes. Last weekend I talked a suburban friend into walking to the mall. The obvious route provided by our urban planners for pedestrian access seemed so round about that I kept my eyes peeled for alternatives. Yes. Other pedestrians had blazed a trail. I noticed a chain link fence with a man sized cut and a worn path. Then I noticed some conveniently placed stepping stones in a drainage ditch in front of a storm sewer culvert. Yes. If graffiti vandals can get in there we can too. The pipe led under the train and metro tracks. I think the short cut saved about 15 minutes each way over the urban planned route. The straddle legged walk needed to keep the feet dry wasn't so bad. I think storm sewer routing would be good to keep in mind when you're walking somewhere and faced with a car centric obstacle.
