The record for memorising the digits of Pi, certified by Guinness World Records, is 67,890 digits which was recited in China by Lu Chao in 24 hours and 4 minutes on 20th November 2005. (Mr BS note: Jeez some people are sad!)
The cache is hidden close to a large parking area. If you have time, make the short walk along an obvious path up the 'spine' to a small knoll for even better views. (Now a wide track leading to a look-out place complete with pergola)
The cache is a small lock 'n lock box.
