These pictures are rotated when seen as a thumbnail... I don't know why. If you click on them they become right-side-up.
I saw someone at the TSP using a foldable cart like this one to haul his gear down to the field, and I had to get one. This one is from Costco, although they're available from other sellers including Amazon. My telescope case is 30.5" inches long and is a good fit for the cart.
Larry Bell is the artist. The exhibit consisted of many 6' x 6' glass plates attached in pairs at right angles. Some were tinted, some were partly tinted, and some were clear. If you haven't been to the Chinati Foundation in Marfa to see the art you'll enjoy the visit.
