Take sun cycle in to account as well, I'd say try to get the longest day time Saturday, that way there's only a few hours of true darkness; giving lots more time of the grey dawn The High sun and heat will also push forces into the woods to retreat from the scorcher, should help keep people moving; but of course hydration becomes an issue on these days for some. Also a three day weekend would be a good choice too, so the majority of us have that Monday to snooze a little before work haha.

Condoms do not guarantee safe sex any more. A friend of mine wore one and was shot by the woman's husband!
