I have not gone to this before but I am going to this year! We always go their Christmas event and what a blast it is!
Don’t forget that you can park at the Tri-Rail and make a a day of it! The train station is very very close to the Bass Pro Shop and the Fishing Hall of Fame.
Do a craft, get a free picture with the bunny, and then spend a couple of bucks on hot dogs for lunch! Lots of Fun!
