Head into Sandy Point State Park. Plan to get there early as the traffic backup getting into the park can get pretty heavy as the race approaches. Also be sure to display your parking permit (provided to registered kayak volunteers) so that the gate attendants will let you in for free. There has been some confusion about this in the past, so ask the gate attendants to call their supervisor if any issues arise.
You can unload your gear by the small craft launch area (left turn just before the last parking lot before you hit the water; there have been years past where someone put up a road closed sign, but that is not correct – just go around it). The image and dashcam video below shows a map of the area and where to turn (hint: follow the Jeep). This has caused significant confusion in the past, so please make sure you understand this.
