Even though it is only $6 to get in, this is so old school.  They hand you a 3 ring binder to take you through the tour.  They do not have information cards at each fire truck.  You have to read this small print in the 3 ring binder while minding your children.  The old guy at the front desk was grouchy on top of it all.  Don't waste your money.  Make a donation to the fallen fire fighters instead.
