A cane may be the only option. From what I’ve read, no weapons of any kind, pepper spray or mace are allowed into Trump’s rallies. Rally goers are almost completely vulnerable when they leave the venue.>>> that’s a shame. I carry mine and my baton into work everyday and one is attached to my bike. i have a cane as well.
A belt with a nice heavy buckle works well to help clear the way. Easy to take off and swing away.
Works great when surounded.
