That's the way to go. Just remember when you get to exit 59 on 287, it goes to the left or right. Make sure you stay to the right and follow 208 S toward Franklin Lakes and you should have no problem.
To answer your other question...you get all ages at this show and all types of cars, but there are a good number of 1st and 2nd gens there on any given night. It seems the guys with the F-bodies are mid-20s (like myself) or older. But I hear ya. I get up for work 5:30 each morning, so during the week I'm pretty much a dork...man I wish I was still in college
