I plan to figure out where downtown Cleveland is, and drive there. Also, to go to Trader Joe's for some basics. (I am running out of Manchego cheese, for instance.) Maybe I will also try to figure out where Lake Eerie is. I'm told it's very big, so it shouldn't be hard to find.
If anyone has any opinions about things that are nice to see in Cleveland that don't involve going inside, do mention them in comments.
I am definitely getting cabin fever, at this point, despite how nice my little apartment is.
