I found this in an email from a local group here in WNY:
Here are some Do’s and Don’t’s for attendees of the March on Washington:
While participating in the March on Washington, you will be under the jurisdiction
of the United States Capitol Police. Here is a list of things to remember on Capitol
Grounds:
Signs with supports cannot be more than ¾ of an inch in diameter at their largest point
Sign supports must be wood and must have dull ends
Supports cannot have protruding nails, screws, or bolts
Signs cannot offer items for sale, solicit contributions, or engage in commercial
advertisement of any kind
Signs are not permitted within Capitol buildings
Tents, camping equipment, bedrolls, or shelters of any kind are prohibited
Do not climb, remove, or damage any statue, seat, wall, fountain, or elevator tower,
or any tree, shrub or other landscaping feature
Do not offer anything for sale or solicit contributions on Capitol Grounds
Firearms, explosives, clubs, missile, or any other weapons of any kind are prohibited
Open flames are prohibited
Failure to abide by these rules governing the use of Capitol Grounds could result in
fines, arrest, or both.
Remember, above all, be peaceful and respectful. Do not give them any reason to
discredit or dismiss us!
