Is Carlisle show best to attend? I need help

[DADS71]

Hi Guys I restored my dads 71 cheyenne big block. My dad turns 80 july 4th . We show the truck locally and took it to maggie valley for the nats last year I was wanting to do something special with dad this year and go to a big show but don't know which one to attend, looking at super chevy which we done last year in indy we done a good guys locally last year. Carlisle looks good but its 700 miles from the house. but I was going to take off a week in aug. any way . Give me some input. Thank You I live in southern Indiana so california is out of question.
