How does one with military vehicles get involved with parades? Do you contact VFWs, local chamber of commerce, etc?
Typically, once you have a vintage MV, and attend a couple of car shows with it, one will get some invites. Also, if you know of a specific parade, many have online applications that can be filled out indicating type of vehicle and description one would like read at the parade. The organizers are usually very happy to have vintage MV's and will place your vehicle with other MV's or a similar class.
There are about seven or eight parade within a half hours driving time from my place, so it is pretty handy for me. Once you attend a few, they'll want you back.
