If you're ever back in Michigan, you should visit the west side ... and also check out lake Michigan. Grand Rapids isn't as big as Detroit, but our economy is growing at a healthy clip and there's a lot of interesting things going on here.
Actually, I was at ArtPrize this past year. The western coast is beautiful, I got a chance to go to Sleeping Bear and up into the U.P. as well. I'm definitely going to head back there to do some biking.
