Re:Wild Boar Trip
I have swapped notes with Hot Dog Empire about this trip. He is aware that the Hoffmans and the Mayor and his blushing Bride will be headed to that activity this September, and have promised a detailed review of the arrangements at that time.
As for the trip, Use whatever route you want to the Cleveland area, then SW on I-71 to Columbus, I-70 west to St Louis and I-44 down to the Camp (near Rolla, MO.) Lots of good RF stops in Ohio, Indiana, and Illinois & St Louis. If the boy is into airplanes...a stop at the USAF Museum in Dayton is worth a side-trip...it is the best free museum in the country IMHO. Then do the Arch in St Louis, another very good memory for a boy and his dad !
Mid winter can be a hard time for roadtrips depending on the weather. As a New Englander you are more in tune with this concept, than this former Californian, but be sure to include extended travel times in case of weather issues. A month later might be a thinkable alternative time.??
