We will be staying saturday and sunday night. Might take the new boat out for like a half day on monday and then start driving back to missouri
Too bad you can't stay longer. Monday and after should be nice boating once everyone goes home.
Does the new boat have a cover? Sometimes that can help deter quick, sticky fingers.
Maybe call some of the storage facilities and see if you could rent a spot for the night?

What kind of boat are you picking up?
