That sounds like the one I mean. I think I saw some pics of it Crawdaddy's original Grand Canyon Loop RR. And I think his tracks also show the locked gate road.
I don't what we will really do on our next trip yet. But we will probably skip that Mt. Trumbull road.
I have seen some recent ride reports that imply getting gas at Bar 10 is not as big a deal as I used to believe. Somebody mentioned that they seemed to have plenty and only charged him $7/gal.
I guess this is getting a little too far off the GWT subject.
