Description   EN   

NOTE: This listing is an example of a benchmark cache type, in this case it in an example of a Canadian benchmark listed in the CGS-NRC database. THIS IS ALSO AN EXAMPLE OF MULTIPLE STATIONS AT A SINGLE LOCATION (the pillar itseff is "PIER 1 London 813041; the brass "bolt" shown in my photo and attached to the conrete pillar is "98U100". Although it is currently listed as a virtual, it will eventually be converted to the new benchmark type when that is rolled out, or it will be archived and relisted. The final format may change in accordance to the listing requirements once those have been decided. you are welcome to find this virtual cache all the same, while it is still active.

If you are viewing this listing and would liek to make suggestions for the new Benchmark Cache Type, please leave comments on this cache page or in the OCNA forum: http://forum.opencaching.us/viewtopic.php?f=2&t=1820
