I have experience navigating. If needing a copilot is stopping you, i'm up for it. I should be going again this year, but i don't really want to enter my dinged up Insight. I navigated for a few people at a completely different event with good success. It's nice when you have two sets of eyes looking in opposite directions so you can fly through any yield signs
.
Gasoline Fumes lives near the event and spectated last year too. Don't let anything stop you from going! It's a lot of fun. The track is featured in the F1 movie Rush.
