There seem to be 3 organized groups / museums in the Houston area, and just from websites and hearsay, all seem to be mostly focused on WWII, jeeps, full restorations, re-enactments etc. Not so much adaptive use of a a Deuce, which is why I have one. Here is one of the links:
Blue Bonnet Motor Pool
I don't seem to have bookmarked any of the others, but a "military vehicle Houston" search will probably turn them up. I haven't had the time to personally visit with any of the groups.
I keep thinking a Houston area Steel Soldiers lunch meet up would be fun, but never seem to have the time to set something up...
Welcome to the Deuce owners club !
