Most swap meets I go to, at least some of Sunday is break down day and at most almost the whole day is devoted to packing up and getting out. Pate is no exception.
The actual days that are the best are Thursday, Friday and Saturday. To avoid the crowd and see most of the items, Friday is my favorite day. I haven't been to the Pate meet on a Saturday in years. Try Friday next year - I think you'll be much happier and if not, than I couldn't tell you of a meet in this part of the country that is any larger or any better. The only possible exception could be the fall meet at Chickasha, OK at the Grady County Fairgrounds.
