Commuting from McLean for just the second time ever and ran across this predicament this morning around 730am. I biked to other side of the Lyon Village shopping center and not seeing any signs, picked up the trail there. Rode down a ways to come across a truck and a roadblock. Picked up my bike and carried it around. They definitely need better signage – especially for a newbie, staring up the hill of Lee Highway and not really knowing what was up was confusing and intimidating.
