Well we tried to do something with a big orange tarp, but it didn't work or stand out in a meaningful way. (The thing about the checkpoint area at Delray, with the Shack and all the Hobie cats, there are a lot of distracting visuals there.)
Just north of the checkpoint is another graveyard of Hobiecats ... once you see that, the checkpoint is maybe a mile down.
There will be a Redbull buoy just outside of the shorebreak, and a white Best tent will be set up, along with a tall black banana flag. Two single line kites will also be flying off the top of the Best Tent, and the ground crew will be blasting air horns when they see kiters approaching. (If you go too close to a swimming area, lifeguards may blast an air horn at you, but pay attention, and if you don't see a Best tent, flags, a redbull buoy, and a bunch of people screaming, it's not the checkpoint.)
We are bouncing around a couple of other ideas, and will give any updates tomorrow at the riders meeting.
