One of my lab partners from my A & P class is working on this aircraft. Last year, before she completed her testing, she said there were wing spar issues to be dealt with. The staff included folks who worked on F-4's in Veitnam, and they were sorting out the best way to complete an airworthy repair.
She had stories of being popular, as she was small enough to get inside the aircraft to do things older, heavier folks could no longer access.

Last time I spoke to her was just over a year ago, and she said there was a plan to get it airworthy, fly it for a special event, and then park it in the museum. I hope things change on that aspect...but it is actually a very rare, pre-production aircraft; so I can understand where the desire to not chance it's damage in any way comes from also.
They are a small organization, but last year they managed to get two Hueys cross-country to attend a Vet's event on the East coast. Murrieta is off the freeway between San Diego and the Riverside area, so folks heading to see March could easily stop by here. They are on the same feild as this rather more noted around here organization:
