Thanks for the input guys! I'm keepin her parked till Monday when I'm having the t-stat replaced (or at least investigated further). Time for a coolant flush as well before winter anyway. My indie echoed the t-stat suggestion as well. Again, the forum's proved to be an invaluable sounding board of experienced owners!
After that, I'd be happy to take you up on that race Tracy!
Oh and after the snowshoes (Nokian NRW's) get put on too.
