Great idea Larko, awesome and just to ad my two bobs worth, the perfect accompaniment to the Storm-Riders GPS Challenge Trophy comp! I'll be there if I'm free that wk end, for sure.
For your information also and if your looking for local cabin/unit style accommodation, you could give Sandpiper Lodges on Smiths Lake a call? As Smiths is full at the moment, it too could provide another great location for a wk end of slalom style GPS racing. It's actually perfect in a south easter if the NEster doesn't eventuate
