We are in the Tyler Azalea District and the streets are paved with real ceramic brick laid down in the 30s. They've worn and developed a little concave feature that was holding a few drops of water. You can't even see it unless it rains. The squirrel was going from brick to brick drinking these little pools of water.
I thought about where the nearest open water is from the studio. It's about four hundred yards or a little less down to the rock lined creek. Probably beyond this squirrels territorial range.
I've seen them wire walk and climb brick buildings but I had never seen this before.
Earlier we were watching a squirrel across from the coffeeshop that is notable because of his tail, broken and hanging limp in the last 1/3.
