Ok I'm stumped and need help

I know that several of you read the blog...and now I need some inspiration from you. We have our next meeting on April 11 (or so) and I had slated to do a try it on the Upper Penninsila (sp?) but some how that just doesn't seem to do it for me. I can't rely on the weather being its April and Michigan to plan something for outside. But feel like the kids need to get moving. Anyone got any ideas for try its?
