K.V.
grab a baby back pack and take off in the woods. We did this with a large 9 month old. She will love looking around at things and will fall asleep easily because she is cuddled close to you. You can go camping (take the playpen and set it up in the tent). You can do a biking trip ( bike seat or borrow a trailer for her). There are lots of paved trails. Hire someone to go with you (to watch the baby) and you can even do Cedar Point) We took a twenty something nephew and his girlfriend, and we all took turns staying with the baby, and riding, we paid for them to get in, and we got to ride rides together.
