Also, slow down in the construction zones, esp. the one @ the Briley Pkwy & I40, as it was being "monitored" hnoes
Also VERY IMPORTANT - there is a prime spot to "open it up" between exit 22 and exit 28 on I65 however, heading N. towards the museum, there is a hill that crests before exit 26, where cars sit and monitor traffic.
Also, while heading to the airport last weekend, I stopped for gas near Opryland. When I took my exit, I was in front of the Opryland Hotel which much to my surprise, across the street, there was ANOTHER cool museum: museum link
