I think our best bet is to park between turn 3 and 4 near the Country Crock camping area then take Pitts School Rd to Roberta Rd then over to 49 and then take that all the way to 49 and 85 or 49 for 485 South. Hopefully we will have options (doubt it since they tell you which way to turn) but the scanner may help. I was planning on parking next to Sam Bass and taking Morehead to 49 but figured it will be too long of a walk from our seats on the front strech to the truck and 1/2 of the place will be on the road by the time we even get to our truck.
This time is a lot of planning and questions, October and there on will be a lot easier and enjoyable since we know what to expect and hopefully what to and not to do.
When I went to the 600, I parked in a grassy area past the bridge (but before the lots) on the left off of Morehead (heading towards the track). My seats were on the front stretch so it was a bit of a walk... but it's really not that bad. The walk will seem a lot shorter if you enter in Turn 2 and just walk under the bleachers until you get to your section.
I live off of 49 so after the race it was a straight shot home and traffic really wasn't that bad even though we weren't the first ones to leave. Traffic moves fast on that end of Morehead because there isn't much [if any] pedestrian traffic. The closer you park, the longer it will take to leave. Most of the people that park on Morehead head for the lots close to the track, which forces them to leave onto 29.... bad idea as traffic is held for people to cross.
You sound like you've got your hands full, but see if you can find room to bring a small cooler to pack some drinks and sandwiches/snacks (chips weigh practically nothing)... food at the track is expensive. If you do decide to bring a cooler, it'll be a pain to carry to the track (ice + drinks = heavy load)... but after the race it won't be bad since it'll be empty (or should be).
Oh, and take 49 to 85. 485 takes forever to get back to 77. Have fun!
