I loaded up my OTG and WSM for a 4th of July picnic.  First time I've ever taken them anywhere, and like everyone else, no problems. I used a little WD-40 to loosen up the legs, but it came apart quick.  Moving it gave me a good reason to give it a thorough cleaning.  I was actually surprised at how easily the WSM travelled.  Biggest problem was that my car started to smell like grill, which got to be a bit much.
It was so nice, too, having it set up in a park next to the river, as opposed to the back yard.
