Bristol Motor Speedway - looking for tips, folks...

[a_d_a_m]

My dad and I will be attending the Bristol NASCAR race in a couple weeks, and I'm just wondering if anyone in the area has any input on the best way to get to/from the track, where to park, stuff like that. Quite frankly, I'm not seeing anything in the satellite pictures (or the track literature) that says where to park.

We are staying in Glade Spring, Virginia, as that was the closest hotel we could find at the time, and now we're already booked.

Anyone know of any good backroads to take there to avoid a lot of the traffic? We are taking dad's Mustang, which handles like it's on rails as long as the roads are smooth.
Roads to avoid? (dirt, bumpy, high traffic)
Where to park? (on the north/northwest side of the track, don't mind walking 1-3 miles but beyond that...no thanks)

I'll accept any input whatsoever. Dad and I have been to many tracks, but this is our first time at BMS.

Fans coming south from Roanoke or Wytheville on southbound I-81 are encouraged to exit at Virginia Exit 17 (Virginia State Route 75) in Abingdon and follow southbound Route 75 into Tennessee, where it changes to Tennessee State Route 44. Route 44 intersects US 421 in Holston Valley; go north on US 421 and turn left on Tennessee Highway 394, which will bring motorists into the Dragway side of BMS. There will be directional signage along this route to guide you to BMS.

Fans coming south from Virginia on southbound I-81 can also exit at Virginia Exit 3 in Bristol (Interstate 381), which turns into Commonwealth Avenue in Bristol, Virginia, and Volunteer Parkway in Bristol, Tennessee, which leads directly to BMS. Fans may choose to turn left from southbound Volunteer Parkway to Tennessee State Route 358 (Weaver Pike) to reach Tennessee Highway 394 and get to BMS on the Dragway side. All of the traffic signals along Commonwealth Avenue and Volunteer Parkway may be manually coordinated to optimize traffic flow both before and after the race as conditions require.

No way to avoid the traffic. If I were coming from the direction you're coming from I would park somewhere near the drag strip, if possible on the side of the street that will put you on the road home without making a left turn to get on the highway... It will be a couple of miles to walk, but you will have a better chance of getting out after the race.

Thanks - both responses help!
