Signature Item 签字物品

这是在Jellyfish的event中提到的概念，之前我没看到过，这个翻译也只是直译一下，google了一下，解释如下：

A signature item is a unique item that a geocacher leaves in a cache that's his or her way of saying, "I was here." It's sort of like the Lone Ranger and his trademark silver bullet. Signature items can be anything from a printed business card to a handmade clay sculpture. (To give you some ideas, the Michigan Geocaching Organization has a database of photos of signature items on its Web site

基本说的就是Signature Item就是代表主人说：“到此一游”。从看到的一些解释来说，sig item好像是可以被拿走的，当然有out 就应该有in。

查看中。。。

有个人做了个站为sig item做track http://www.sigitem.com/

Signature Item我理解是一个个性化的纪念物，表示“XXX到此一游”或者说“我来过了”，比如佐罗是划个“Z”作为证明。

:L那么哪些是可以被拿走啊？搞糊涂了

某某到此一游。。

为什么20贴才能查看藏宝信息。。
