There is a saying here in Indiana, "If you don't like the weather, wait 15 minutes!"
I take my coach up in March, by that time, the snow season is starting to slow down, and if it does snow, it may not be long on the ground as March can come in as a lion and leave like a lamb.
But - Nappannee is up north and is subject to "Lake Efect Snow".
I would say mid March and beyond you will be fine. And 31 is the way to go.............
