Iron Butt SaddleSore 1000

I've signed up for the "SaddleSore 1000" certification ride June 4 sponsored by the Iron Butt Association: 1000 miles in under 24 hours. The route is from Houston to Fort Stockton (500 miles) and back. It should take about 18-20 hours of riding including stops. This has become a sort of right-of-passage for dedicated motorcyclists, and I want my stripes.
