GC8J6DJ - Sherlock Mystery Meet & Greet

I just heard about this potentially cool activity happening in the Seattle area in the week between HQ20 and GWXVIII.

If you like Going Caching, you just might like this - Sherlock - A Novel Cache. According to their website, this is a seven geocache geocoin hunt. Each cache represents a "witness" that you will need to "talk" to in order to deduce the location of the final, or "M," and open the reward prize. In order to participate, you need to order a Sherlock game hunt package, which will contain "vital case files, information, directions, exclusive event swag and a trackable prize solution geocoin!" These packages can be picked up at HQ20, the Sherlock Mystery Event, or, if you're staying at the Issaquah, WA Hilton Garden Inn, it would be delivered to you (maybe directly to your room???).
Apparently, if driving, this activity should take one hour to complete, if walking, two to three hours. I think it will be a great time filler in between the big events and I think I'm going to shell out the $40 to pre-order a package.
