We got some fried dough and decided to walk the beach and dunes. The moon was nearly full and it lit the dunes perfectly for exploring. After a while ...alking we needed a break so we sat in the sparse grass between two towering dunes.Leo and I had planned to smoke a little weed with Lindsay because she made it clear she was into it. Amy had said earlier she didn't smoke. We asked Amy if she'd object if we smoked and she didn't. After a few drags Amy was watching seemingly with envy. I offered.
