Traveling from Massachusetts to Indiana in June, have made

[yy4me]

this trip before by driving from Boston, to Scranton PA, all the way across Penna, Ohio then to Indiana. Anyone know a good alternate route across that will be less boring than the Penn Turnpike? Have not done the map route yet, looking for inspiration(and Antique shops for poking around). Any suggestions with sights and shops? We have 3 days to get there, 4 days there, 3 to return. Thanks for any ideas.
