A bonus to the local AdLabs, set due to peer pressure ;)
The cache isn't at the given co-ords, although you may find parking close by. It is well within two miles/3Km of here though. To find out where, complete the AdLabs and read their Journals.
The cache is at N51 PL.ATY W000 JU.BES - which nearly works as a concept...
Good luck and have fun!
