Ha, Ha, great hats.
Lava tubes................. We have some not to far from me up here, (4-5 hours), Same here as some of the tubes have collapsed. Pretty dry country where the tubes are and where they have collapsed there are pockets of rain-forest growing in them.
Bid difference in the country and tubes
