Welcome!
Went to BG and know the area well. Not much for roads, but there are some fun ones to keep you occupied. 105 to Woodville, 65, 424 from Napoleon to Defiance, and further south you can run 12 from Findlay to Columbus Grove.
You can connect them all together and run 105 to 20...run over to Fremont and hit 12 all the way to 115 north to Defiance. In Defiance hit 424 to 65 and back home.
Finish the ride off with Myles Pizza (don't forget the cheesy garlic bread) and everything will be right as rain.
