If you're looking for something to do this weekend, consider Ada's Harvest and Herb Festival. Ada is just a short 20-30 minute drive from Findlay.
This year marks the 35th annual Harvest and Herb Festival in Ada after a year hiatus due to the pandemic. The festival will take place midway through downtown on State Route 235 and it will begin at 9am with a parade beginning at 10am. After the parade there will be all sorts of street vendors, craft booths, and plenty of food trucks to browse until 4pm. This is an all outside event so be sure to dress appropriately for the weather. This is a free event so it costs nothing to attend.
So if you're looking for something to do outside that's free, this might be worth checking out!
