Jeff,
We will fill in where the pattern guys before us empty out I believe is what Dan K told me. They are suppose to end on Thursday. Friday is a "rain" day for them if it should rain on one of their days of competition. When they empty out we will begine to fill in. I dont necessarily know if you can reserve an "exact" spot, but you can for sure reserve a dimension and then team up. Ex: Us JR guys can all get together and decide what we would need and just reserve enough spots to group up.
