A buddy of mine rented a spot a couple years ago. He was able to park his truck & trailer, had sleds for sale, in the main area. It was either $50 or $75, one of the two. I suppose it depends on how much room you need.
Show up at about 5:30AM to get a spot. Space is limited. I think the cost is 20 bucks for two parking spots. Not sure about costs for any more spots than that.
I will be there selling my trailer and some other stuff.
made it to the Slinger swap today for the first time,...well attended on both sides of the table despite the off and on rain.
I found a couple great deals too!
