For those folks who may make a stay of a couple of days, here are some suggestions made by one of our favorite KZoo fans, with research done by SportzFan, for things to do while in Rockford.
PARKSSee, for the life of me, I am clueless when it comes to winter activities, because other than watching hockey my favorite winter activity is staying inside and keeping warm! So you folks will have to help me out with outside suggestions for the winter. The only things that come to mind, based on others' suggestions, are sledding and ice fishing. I don't know where to go sledding, but I believe you can go ice fishing at
Rock Cut State Park.
In fact, let's start there. The above link to Rock Cut lists activities for all seasons.
Another site that might help you out in looking for activities for all ages is
