A topographic map of Washington in 1791 by Don Alexander Hawkins. I live on the top edge of the map, on one of those hills. I’m a generally happy user of DC’s Capital Bikeshare system – just renewed my annual membership today in fact. But I don’t use it as much as I’d like to, for one critical reason. I live on top of a hill. Riders are happy to take bikes from the neighborhood to their jobs downhill, but are much less likely to ride them uphill.
