CITO日，今天刚好从Ianian学习到

April 22 is Cache In Trash Out Day

Every April, geocachers around the world get together and clean up their local parks. It's just one way we can contribute to the maintenance of our outdoor spaces and to say "thanks" to the land managers that help to make our parks a great place for geocaching. Learn about how you can start your own CITO event, or just how you and your family can CITO every time you go geocaching. Visit CacheInTrashOut.org for more information.

Let’s clean up our playing fields! Cache In Trash Out is an activity intimately tied to geocaching. While out there on a cache hunt, we collect litter along the trails and properly dispose of it. On certain days, we also participate in much larger clean-up events that involve and benefit the larger community.

Groundspeak is again sponsoring International Cache In Trash Out Day. This year, our fourth annual event, it will be on April 22, 2006. Together, we make an enormous positive impact with just a little joint effort.

哈哈，正好是个周六。要不正好活动一下？

外国人的节日一般都是每个月的第几个星期六，星期天什么的，就是让大家在休息日搞活动的，中国也应该学习一下，要么就放假。
