Track-Day Hiatus

I've researched my insurance coverage, and it turns out that USAA won't cover my car when it's on track, or near the track, or thinking about being on the track. I had somehow come to the belief that the car would be covered because HPDE classes are not timed events, in other words, not races. Clearly, I was incorrect. I looked into supplemental coverage, but the premiums are somewhat high, and the deductibles are exorbitant. Thus, I've put my Miata-tracking plans on hold while I look into other alternatives. I may have more to post about that later.
