3 Day Trip on the Middle James in VA

I’m planning a 3 day kayaking trip on the middle James in September. I’ll be going from James River WMA launch to the Hardware River WMA take out (aprox 25 miles). I planned on finding a random spot to camp the first night, and then camping at Horseshoe Flats Campground in Scottsville the second night. Campground seems close enough to check out downtown Scottsville for the evening. Anybody done this trip or something similar? Any recommendations for camping the first night?
