Brian,
I live south of you and can attest to the hilly and forested landscape you describe. I am in the foothills of the Appalachians, so chasing here is almost out of the question since you can't see any distance for the terrain and due to the roads being made as if a snake's path was followed during construction. If I head west of I-75, things start to improve a bit. But in my immediate area, chasing is a no go. If I want to see storms here, I don't chase, I intercept. With good data (a smart nowcaster....or WxWorx, whatever you have), you can try to get to a safe point in relation to an approaching storm in which to observe it's passing. In the process, you hope you see something cool as it comes by. If you have time to reposition somewhere else, then great. But the speed of the storms, the poor roads and the terrain often mean it would be impossible to actually try to follow a storm or get too close to it's path. It's just too dangerous.
But all is not lost. Much of western Ohio, the northern half of Indiana and much of Illinois is flat and has fewer trees. If you want to chase without driving 800 miles to get to a target, I'd look at venturing into these areas when the opportunity presents itself. And as far as your local area around Cincy, I'd stick to more static "observing" by positioning yourself S of approaching storms at a safe distance but where you have a good view. That's about the best we can hope for in hilly areas. It's like spotting, except you also have a cam. Hehe. But remember lightning and stay inside your vehicle. The advantage elevated positions provide in visibility also put you at greater risk for those lightning bolts that come crashing down.
