Administration has decided signing day should not be a major fund raising event. They want it to be a day of celebration and of saying thank you to the supporters. There will be a change next year however. RCAF members will still get in free while non RCAF members will be charged a nominal fee. Idea there is for your RCAF membership to be more valuable. I suspect the large majority of fans at the function are RCAF members so this probably won't be a big deal.
