Today, as on most weekend days, I ran in Rock Creek Park. Along Joyce Road, I saw a young woman walking along a guard rail. In the park these rails are made of treated lumber, six by eights I think. So it is not especially difficult to walk along the rail; but I couldn't tell you when I last saw someone doing so. Then on the way up from Beach Drive to Carter Barron, I saw a young couple walking on the guard rail there.
Why are people now walking along these rails? Is it something on TV?
