The private tour is for two individuals to get an "insider's look at the "best place to work." In fact, this is being organized by Foundation for the Future, an organization that "raises private funds that allow Menlo-Atherton High School to address the real-time needs of its diverse and high-performing students." Note that the winning bid will go in its entirety to the foundation.
If you win, you get to pick a date on the weekdays only for a two and a half hour tour, which includes lunch. Only catch is you need to pick a date before July 31, 2008.
The eBay auction runs until Apr-20-08 21:00:00 PDT and the current bid is only $265.00, with 15 bids already. So, if this is for you or if you just want to give a nice donation, go to the eBay listing and bid away.
