Wannabe1-You might try chasing them in the coast range as well as over East, there are tons of yodel dogs on the wet side. I've seen lots of coyotes working the edges of clear cuts and got a shot at one from a tree stand that was set up on a trail in big timber adjacent to some second growth.
As for the statement that they aren't very tough, my experience is that they can take a licken' and keep on ticken'. I made a marginal hit on the one mentioned above, right where I was looking-dead center-likely a liver hit, and he dissapeared into the fern and alder jungle. When shooting at one, make sure you pick a spot just behind or on the shoulder blade. Stay well concealed and watch downwind, they almost always come in from downwind when calling. Get after 'em guys!
