Riding Patuxent

The Examiner had a nice little article about biking in Patuxent Research Refuge. I've never biked there, but I have ridden the WB&A trail which is in the same area, and it's very pleasant. The wildlife refuge is where President Bush was famously biking on the day Capitol and White House were evacuated due to an errant Cessna flying into the restricted airspace. He was biking the Central Tract, but we're not allowed to (it must be nice to have your own place to ride). Still the North Tract (not to be confused with the one in Arlington) sounds like a place worth checking out.
