If you go over there, as just a single Veteran to visit your WALL, then you don't have to have a permit...I've gone to several of these, and ain't never worried about a permit...there is no law against, or permit needed for as many veterans as you want to, in order to go visit the wall....if there are organizations there with permits, and it makes you feel better or more legal, then I'm sure they will let you sign on with them.....in other words, don't let not having a permit stop you from being at "your" wall on March 17th.........
