Right around 1:00 p.m., the sandman will usually start tugging at my eyelids. It always seems to happen when the early afternoon sun starts to warm things up. I seldom fall asleep, but I often close my eyes and teeter on the edge of consciousness. Hearing a couple of deer crunching through the leaves sends a shot of adrenaline through my body though, and once that happens I am good to go for the rest of the afternoon and evening!
