One of the District’s most appealing sledding hills is usually off-limits — Capitol Hill. But Del. Eleanor Holmes Norton (D-D.C.) is trying to lift the sledding ban on Capitol grounds, at least for the weekend.

The congresswoman wrote to the U.S. Capitol Police Board Chairman Frank Larkin on Wednesday requesting a waiver of the ban from Thursday through Sunday, after another snowstorm is expected to cover the region.

“This could be the last snowstorm the D.C. area gets this winter, and may be one of the best for sledding in years,” Norton wrote. “Children and their parents should able to enjoy sledding on one of the best hills in the city.”

Norton said it would be a “one-time waiver … while we await a more formal review of the ban. She sent a similar letter in February to no avail.

Sledding on the Capitol grounds has been forbidden since the Sept. 11, 2001 terrorist attacks, as a security measure, with the exception of a one-weekend waiver after then-Sen. Chris Dodd tried to take his daughters sledding there in 2010.

Becky Levin, a Capitol Hill parent, said she did not know about the ban and took her seven-year-old daughter to the Capitol, the closest and most scenic hill she knew of, during one of this winter’s many storms. After one run down the hill, Capitol Police came over and asked them to stop.

Her daughter was confused. “She said, ‘Are we breaking the law?'”

Levin said the rule confused her, too.

“Not letting kids play in the snow? That seems like an example of over-regulation,” she said.
