Hi. they are open by appointment during the week and on Sundays beginning at 9:00 am. I was there last summer on a Sunday. It is very diffiuclt to enter. You have to make a U turn on Tonnelle and come back on the entrance if you come off the Skyway. You also have to wait for a red light getting out and hope someone lets you out of the driveway. There is only room for one car in the driveway too. Good Luck. Rose - researching SCHICK, MORRISON, KREINER
