We actually pulled up into the parking garage for the Gateway Arch, got out, put all our rain gear on (it is about a 3 block walk from the parking garage to the Arch), stepped out to the edge of the overhang, watched the rain coming down sidewys for about 5 minutes, and decided the national monument wasn't worth our own personal discomfort, so we loaded a couple screaming, and disappointed kids into the Tahoe and pressed on.
The Magic House (St. Louis Children's Museum) was next on our list, and once we got there I think the kids completely forgot about The Arch. The Magic House lives up to its name. We spent 3 hours in kiddy Valhalla.
Lexi enjoyed applying one of her studies - the tangram. She just finished a story "Loawnu and the Fallen Ssky", which is about a women who put the sky back together - like a tangram. At home, Lexi had even made her own paper tangram to play with. So, it was a wonderful surprise to see, and play with, the tangram display at the museum.
The little ones enjoyed the water play - they stayed there for over 30 minutes. Maia figured out how to make a dam and spent hours rearranging the water.
I know the kids could have stayed a lot longer; however, the adults were EXHAUSTED! At least we all slept good that night.
