This is the biggest travel bug I have seen so far. will pass him along very soon. Although, because of its size, I may not be able to drop it off at just any cache. My dog is actually into his second week of recovery from Knee surgery. I have rubbed his knee, but im not sure the pain releif will work for a dog. He did give me an odd look. Im sur ehe would love to get back out caching with me, but he has 4 to 6 more weeks of recovery.
