Let's run in the Glen Artney area of Patapsco Valley State Park.
The route I have in mind: Soapstone, Santee, down Convent/Nunnery, Grist Mill, up Vineyard Spring, Soapstone out with an optional trip up/down Bull Run. Route will be similar to this Garmin map: http://connect.garmin.com/modern/activity/504430069
Total distance should be 5-6 miles, with some hills, roots, rocks, and minor stream crossings. Sunset is 8:04 pm so we should be OK as far as daylight.
A trail map is available online, courtesy the MD DNR:
http://www.dnr.state.md.us/publiclands/pdfs/patapsco_avalonmap.pdf The run is in the purple/yellow/red splotch in the upper right.
There is parking along South Rolling Rd, where the Soapstone trail starts. Approximate address is listed as the address of the meetup. If that lot is full, park at the nearby Park-n-Ride (195 @ MD-166) and walk over.
If people are interested in eating afterwards, we can head into Catonsville to Chef Paolino's (726 Frederick Rd, one block North of the Frederick Rd and Bloomsbury/Ingelside Ave intersection).
