Hey Mike. I looked up the address, it's on Hoselton Rd., but the place where mapquest puts it is definitely not the location. I just drove out of the main terminal's parking lot, bearing right. The store was on the left fairly soon after, and before hitting the developed area of town. The store is actually owned by the Congressman for that district along with several other developments bearing the name "Pike".
I could not find the place using Google satellite images. I think that it is a fairly new place (last three years). The cockpit of the DC-6 was put up within the last two years, that much I do know. It is not accessible from inside the store, and is gutted internally, I believe. Still looks cool though, and it got me in the store to buy an icecream.
With respect to the H-21 on Elmendorf, I honestly can't remember where I saw it, but I am sure it's there. I remember reading about it before I went too. I didn't photograph it... didn't want to jeopardize my F-15 ride at the time, as you can imagine!
There are several other aircraft around the P-38G on display at Elmendorf, including an F-102, T-33, F-89, F-4, F-15 and a C-130.
One other thing, there was a disassembled former Mexican Air Force T-28 at the Brooks Fuels facility (owners of the Carvair) at Fairbanks.
Also, if you want more information on the stuff at Wasilla, you can find some recent images on Airliners at this address...

Oh... and don't forget the Lady of the Lake... B-29 in the lake at Eielson AFB.
pretty cool place to visit!
Cheers. Richard
