Sally, it takes me more than a day to see just the quilts, so I always allow at least 3 days at the show. You have a year to train for it, so if you start now and walk a few minutes each day and then increase your time, even a 200 pound person can be in better condition in a year. I do this, too, to get into training. I no longer weigh over 200, but I do still have at least 40 more pounds to lose, but I can walk for quite a long time now. IIRC, the area on the first floor that's vendors and quilt displays is around the same area as 11 football fields put together, with aisles to walk up and down, so I don't know how many miles it would take to traverse all those aisles, but it's well worth getting into condition to do it. The west end of the building has been used as a restaurant area in the past, so I'm not counting that end.
