Also wanted to mention that I went ahead and booked myself a spot on May 13th-27th. I've investigated radon and specifically the Montana mine pretty extensively so I'll be interested to see how it turns out.
I'll post some updates while I'm there per request of snowshoe and orch and others. I also should mention the operator of the mine is named Pat and she is very amiable and quick to reply to any emails she receives.
