Once when I had locked myself out of my motorhome at Joshua Tree natl park, I knew I had a door key hidden in a storage bin. I Knew the bin key was a 751. I also knew it would take two hours for someone to come to jimmy the lock becaus I was at the south end of the park, so I stopped every RV asking if anyone had that key!!! I was so frustrated because there were mostly small trailers or popups stopping by. No one had basement storage, and it was a very slow day so I ended calling CoachNet anyway.
If a Class A or C had driven by, I was prepared to run into the road with my arms flailing!!
People must have thought I was a crazy lady asking if they had a 751 key!!
I got to know all the Rangers well, and I am afraid they still remember me. Check off one national park I can't return to.
