Find that spot by the river just down stream from the RR tressle....if you can get to it, that's the best spot. It's got a nice sandy beach and there should be plenty of space

If you're coming in from Kelvin Hwy and taking the side road to the river, the spot I'm thinking of can be accessed by a side trail to the west down a sand wash (the same way you'd exit from the river crossing from the Coke Ovens). This sand wash is about 1/2 -3/4 mile from the river on the main road, if that makes sense.
