Looks like such fun. Are you all going to Michigan together? nice... I love crystals too up here in MN in Tower Mn where our fajily resort was for forty years the Tower Soudan mine has 27 levels.. you can hit it up. My husband who has passed on . he writred the whole i mine shaft.. and on the 23 level is an entire level of CRYSTYALS it is incredible and no one can go there but staff who work there. The 24th level is where tourists can go see how the cadilac mine here was run... it closed the year we moved to Ely and bourhg our resort Egales Nest Lakes Resort.... ran it forty years mom and dad and I did..... but the mine is an Iron Ore Mine and mostly rock.. not like the red sand mines in Ely mn that were dangersou and killed many with fast mud slides...... so where are you hdeaded and who all is going.. back with you . Blessings and joy to you xx Merri Mc Elderry in Northfield mn now.. southern mn moved as my son needed a liver trhansplant here and is healed already after three yerars healin gup he is well. Love from us Merri and cat Bart x
