Iron Butt Association National Parks Tour Master Traveler Award

This sounds ambitious, but it also sounds like a blast. I have already seen about 15 NP or NM are in the last 3 months that would apply to the 50 required parks. I suppose I could try for another 35 in the next 9 months but the 25 different states is what I find daunting. That’s a bunch of mileage even for a seasoned tourer.
Anyone done this??
