If you guys get the chance to link up with your local PGR and do a mission with them, you will get the feeling for exactly what we (the PGR) do. You do not have to own a motorcycle to do the missions with them. There are several people that do not own a bike and come on the missions in their cars.
I have rode with the Oklahoma PGR for a little over 2 years now when I am actually stateside and able to. My very first mission was a funeral for a 19 year old soldier. The protestors were present at that funeral but the Highway Patrol, local PD, and one of the other local bike groups (Rolling Thunder) kept them further away from the funeral than the law actually requires. Most of what I have ridden with them has been funerals, but I have done a couple of Welcome Homes at the airports.
I have personally had 2 Send offs and 2 Welcome Homes for me by our local PGR and can tell you that it makes me proud to be a part of what the PGR does and stands for. I am actually done riding with them for a few years as I am now stationed in Germany and will not be able to, but I plan to link up with the local PGR wherever I get stationed when I return stateside if I am able to.
