I thought of it at the last minute and wanted to post it so other people wouldn't forget. My Driving License and Registration expires while I will be hiking. I was able in Ohio to get a new License 5 months in advance. The only difference is that it expires in 3 years instead of 4.
I was not able to renew my registration. But I was able to get a form that allowed someone else to do it for me if I filled it out.
Hope this helps.
