I can not help but think that Rock Creek Park has so much more potential than the NPS realizes
I also can not help but think... just as the city of Washington DC offers baseball fields, astro turf soccer fields, basketball courts, swimming pools, and tennis courts
the city of Washington DC does nothing to support the sport of cycling
legal mountain biking in Rock Creek Park would be a great answer
get more kids on bikes
get some of the bikes off the street... away from cars... and into the woods
it would be cheap... JUST TAKE DOWN THE NO BIKES SIGNS
then...
IMBA... MORE.. and other trail groups would work to make the trails better for all users
