Stop in for a cup of coffee

So I have a crazy idea. Because they moved me around from my reserved seat on my return flight, United is giving me a discount flight anywhere in the US. I need to see what the closest airport is and maybe I can fly in vs driving in.

I think it’s unrealistic at this point in thinking the dart could be done by then. I just have too much left to do.
When we fly in we go to Harrisburg. I think from the airport is 25 miles to Carlisle.
