Just wanted to drop a note that Hong Kong Geocaching scene is happening a lot on Facebook where there's a facebook group "Geocaching Hong Kong" where geocachers and newcomers gathers for hiking out into the hills of Hong Kong! All in the name of geocaching.
Do drop by if you are coming to HK for geocaching. We had geocachers over on several occasions and we all had a great time hunting through the mountains in Hong Kong. Not to mention, the FTF rushs!
