Bear, Mine went up about the same time frame, maybe a bit sooner... I was restricted to the square footage of the house and no higher. That precluded a second story and due to a prior install of a ham radio tower the shop gods kept me to 1350 sq feet. I'd sure like to have the extra 150 sq feet I was allowed. Scope creep was about 25-30% over budget and I still don't have the lift in and more concrete is being poured in January.
Nice cave you have there!!!
