Set the clock for just before dawn (6:20AM, or so) and you will get the night points but arrive at the destination in the gathering dawn. The light helps for those back-woods strips.
I have had good luck flying at any altitude I choose (Usually 3,000 - 5,000 feet.) When the co-pilot sees an aircraft, I immeditally turn 90 degrees away from the other aircraft, fly the new heading for a few minutes, then turn back on course. Haven't been caught once since I started using this technique.
