DeltaDelta...We'll be in campsite #24 at the west end of the campground near the lake and the boat launch.
You should be able to find a campsite at the east end of the campground if none of the walkups at the west end are available.
"Even if the fishing isn't good I just love being there and hanging out and hiking around!"...the fishing in Rush creek is usually pretty good...you'll have a blast taking the kayak down the creek...even if it's really windy or the fish aren't biting in the lake...the Creek is a great area.
We were planning on having the crawdad boil on Monday night so your travel plans should work perfect.
