They also picked up MD by moving to SIAC, so the "new" good gates would be MD, Castle and Reitz (but I honestly don't know how well Reitz fans travel to Jasper). No question Bosse, Harrison and Central would be much less gate than Wash, BV & Mt. V. Bosse did have some decent crowds last year being that they were competitive.
Coincidently, Kyle Sokeland has an article on the 5th anniversary of the SIAC expansion in today's Courier.
