Deer Park Rd is great! And it is hard to go wrong in the same vertical corridor as Deer Park. Just a reminder I’ve sketched out some routes nearby but I don’t have a continuous route up yet for your purposes here - http://www.baltimorespokes.org/stati...70815081612328

And anyone can help contribute to this project by sending me a link to just about any internet mapping program (I just need to export a GPX file to get it on my sites map.)
