Not only a great song by the band AC/DC, but a fun geocache hide in front of the Burlingame Dog Exercise Park.
Plenty of AC/DC K9 running room, with water stations for the geo-mutts, free parking, and nearby exercise stations and restrooms. A short stroll through the dog park ends at baseball and soccer fields and is along a SF Bay Path that runs down to Coyote Point (about 1.5 miles). Right across the street is the Bay Trail, also with some exercise stations.
So grab the bone, sign the log, and enjoy your walk (or just sit and stay).
There are a fair amount of mutt-walking-muggles going in and out of the dog park (along with their four lergged pets) plus some other muggles taking advantage of the parking, so please keep an eye open for muggles. Re-hide carefully.
