In Virginia the judges will find you guilty of trespassing!
A sign displayed is not there to kicks. The sign posted is your OFFICIAL notice that some activities are not allowed. This does not mean you can disobey the sign and do "whatever" until someone comes and verbally tells you to leave.
A sign displayed that says "No Firearms, skateboards, or engine repair" means just that. YOU CANNOT DO IT HERE!!!!
The same goes fora sign that says"No Trespassing." It does not meanyou are allowed to walk on the persons property till they catch you.
No firearms = No guns on the property while you are here
No Trespassing = No being on the property at all
