If I want to see a couple of OV-10 Broncos I just have to walk down the ramp to a hangar that holds 2 of them with 1 flyer and 1 under restoration. A guy with an aircraft and armor museum on the airport owns them. A member of our EAA chapter who flew Navy F-4C Phantoms in Vietnam was the chief pilot for the museum and flew it many times and I saw it one day doing aerobatics over my house.
Sadly the OV-1D Mohawk in the 3rd video was destroyed in a crash Nov 1 2019 in Florida that killed the owner/pilot as he practiced for an airshow.
