Nancy, For hunting purposes, the Missouri DOC says you can hunt from half hour before sunrise until half hour after sunset. Based on my experience in deer stands I would say that this would be a pretty good guideline for showing an outdoor movie also. I don't think time of year would make as big a difference as cloud cover. Hope this helps. Sniper1 Mark ************** It's only a deal if it's where you want to go. Find your travel deal here.
