Ran-It Granite is a 3-day orienteering A-meet held a bit west of Baltimore. We stayed in nearby Ellicott City which is a scenic well-preserved town at the bottom of a river gorge – if you can find it amidst all the expressways.

The terrain at Patapsco has an apparently infinite number of small pits, depressions and other holes that can fill with water during heavy rain and then have a flag placed in them for an orienteering course.
