Hello Jobe :-) I floated across the creek on my River Rat Raft and landed in some sand where the warm water was flowing out of the Serenity pool. I enjoyed the sand on top of the rocks out in front of the Crab Cooker too. Alot easier on the feet :-) I'm not sure if thats the sand you were referring too. I measured the creek waters at 45 degrees today. I started to wade across but it started getting deeper quicker than usual so I opted to stay warmer and just blow up my raft :-)
