Hey there, first time logger, first time reader! We are in Northern CA. and have a cache called "Snake Country" it is a large plastic rattler and we placed a micro in it's belly. The cache page has warnings etc "not for the faint of heart" but doesn't let you know what you're in for (although by now the logs sure do!) . We've had the best fun and responses from that cache. It got caught in not one, but two brush fires last year and still holds it's own although it looks a little... burnt!
We also ran into our first rattlers of the season on 4/11. Not one but three, two babies and a mid sized one. Actually was caching in the area of a cache we discovered along with a guardian rattler last June and the owner was willing to archive the cache (and later moved it on). A quick look at the logs told a story of a lot of snake sightings and obviously a den nearby. The cache was called the "Little Bead Cache" and is now.... the "Little Bead Cache No Mo." At least in our area the rains this Winter have got the food chain exploding and we can count on the snakes being out in force this year. Remember: one eye on the gps, one eye in front of you! (funny picture, eh?)
