Here it is almost the middle of May so the season is going well. We have been keeping busy with school groups coming to visit. We enjoy the different classes coming from as far away as Sunshine Academy of Miller, SD
Haven't had many others yet but they will start showing up after schools are out and the weather warms up. We are open on Sundays Noon to 4, and the other days from 9 to 5.
Looking forward to see you!
