I have something just as weird; On Monday May 14, I ride Woodstock Express with my 5 year old. Belt was snug, but I managed (once the ride op told me I was getting my shirt in the buckle). Tuesday May 15 it rained and it would not come close to fitting. My wife, who is smaller than I, but still large, tried and could not get the belt to fit her. We concluded the belts must shrink when it rains. Or we gained several inches overnight. (not!) But the day before I even had my scanner on when I buckled up.
