I work at a state prison and am in a tower most of the night lots of time to watch deer the local deer heard typically bed down in the open for a few hours then they are up and feed for 20-30 min then back down for a few hours. A real good book on deer movement is Moon Struck by Jeff Murray. This has tons of usefull info on rut timing, feeding paterns, and general deer info. I reread it every year.
