That's why I decided to go with an on-road route yesterday instead of a trail. It was quite peaceful. The only problem was the short stretch of Fairfax County Pkwy trail in Reston, which had a couple of snow piles and very cold mud puddles that I had to get through/around.
I did encounter crowds before and after the ride, though. The whole world decided to go ice skating at Reston Town Center yesterday. The guys at Yogen Fruz said they had a very busy day.
