This is not something I would do every year, but every 3-5 years works best for me. If you have never been, you should give it a try. Admission ($12/adult) and parking ($10) is not inexpensive, but there are discounts if you purchase in advance. Lots to see and do: Midway ($28/day M-F); Entertainment; Agriculture; Avenue of States (my fav); Car Show; Horse Show; Crafts; Food & Drink; etc. You really need to plan your visit and see what's scheduled on the day you are attending. It can get crowded, so weekdays and earlier in the day are best times to avoid the crowds. There's also an app for Android and Apple that provides info.
