You must not have had a trailer on when you went through Lima on 309. You can also drop down 65 from 30 but there's a no-truck route on the way. I've used it, but you don't want to get caught on it, especially loaded. Brought you out to 75 on rt 81. We could go straight and use Roush Rd to get to P&G but couldn't come out that way due to a 20 ton bridge.
Sometimes an extra 20 miles is worth it. When I ran wally's-mart groceries out of Auburn (20 miles north of Ft Wayne) I would leave for Kalamazoo and points north, go an extra 23 miles using the interstate, and be leaving by the time the guy who left in the next truck ahead of me got there using the highways.
