I've been trying to get clarification on corral parking for my '67 but no one will give a straight answer to my number crunching.http://saacforum.com/index.php?topic=31972.0
Near as I can tell looking on Mazda's ticketing webpage https://oss.ticketmaster.com/aps/mrls/EN/buy/quickbuy/178
there is a separate corral for the '65/66's. The 3 day entry ticket and corral parking is $190.
If I figure right the other shelby corral and 3 day parking comes out at $215 for the 3 days.
I hope this helps a bit.
