The Mine Tour
Tickets are paid for at the museum to the museum.
All we need to do is give them a count so that they can schedule enough staff.
We are now suggesting that you arrive earlier than the 10:00am schedule time, 9:30 or so. We have almost fifty people attending and there could be a line at the ticket window.
Any questions respond back to this e-mail. Garden State Division
