Personally, I think you’re wasting your time and efforts shilling on the website this week. You should have been doing this before now. The ride has already started; your potential customers are in Cherokee tonight and will be on their way to Lake View tomorrow. They are not at home in front of their computers.
If you want to attract attention for your offerings, you’d be better off putting up signs along the highway, or make handout flyers to pass out in the overnight towns the day before they pass your area. Remember this too — food and beer are available literally everywhere on RAGBRAI; give us something different — entertainment, special pricing, unique atmosphere — some sort of a reason to stop at your place specifically.
