Man are you in for a treat! I assume you watch the race coverage on TV. All I can say is there isn't a speaker made that can accurately give you the sound of a fuel motor.
Drag racing is a pure sensory experience. You will literally feel the sound and power of a fuel motor during both the burnout and during the run as it goes by in front of you. The smell of nitro is addictive. I'm jealous as I missed the WinterNationals this year due to weather and it's been over a year since I've had my "nitro fix". Get a snootfull for me!
Get down in the pits, up close and personal while they're warming the motors and getting the clutches right.
I'm anxious to hear your post race reaction.
And bless your bride for wanting to go too. She's gotta be a keeper.
Post some pics if you get a chance.
