Thankgiving weekends we used to do the traditional meal/gathering on Thursday, head down to the Tough Guy tournament on Friday and then when that was over we would head down to Seaside for a Saturday tournament that they had every year. I loved that weekend and we did it 5 years in a row! Pac-Coast tournament was often done over the New Year's holiday and that didn't phase the turnout. I also heard some people complain about NW Junior Regionals sometimes coinciding with Easter weekend. Oh well, we were always there.
The bottom line is that not everyone can go, or choose to go, on a holiday weekend but for most it is simply a choice. Do what you want, go or not go. I think Gut Check will be a good event regardless of the date.
