About the comment of keeping the tarp low, with my tarp having no doors, would that really help much? I fully understand about trying to keep the tarp with the walls facing the wind, unfortunately, it looks like the wind will be shifting from SSW to basically North around midnight So I'll do the best I can with that.
I do plan on having a little snack or something right before bed. I've got a pretty strong bladder so hopefully nature doesn't call during the worst of the rain. I hadn't thought about having something to sit on when everything is all wet so I may go out and purchase a small self inflating seat for a dry place to sit, and then use that under my feet while sleeping. These ideas about what I hadn't thought about are what's cool about this site. Learn from others!
On a side note, the guys I'm going with may be electing to shorten the trip to miss the rain since they may not be able to find room in the "tent camping" section for the first night out due to the holiday weekend.
So we may hike out half way to the less crowded camp grounds the first day making it a two day one night trip instead of the planned three day two night trip. I told them that as long as I could find trees, I was good anywhere. Maybe this will convert them.
