To answer the question ... What is there to do in Grand Rapids in the winter?

Got to say it looks like they had a lot of fun.

Although, it certainly hasn't felt very wintery lately. In fact checking the extended forecast the lows won't dip down below freezing again until late next week!

Not that I'm complaining about the recent warming trend. These temps are actually closer to the winters I grew up with. In fact this week in my hometown the temps are jumping up to the mid 70s. That's warm winter weather even for there, though, I'm sure my friends will still say 'it's so cold, I can't wear my shorts.'
