Blacktails by far. I hunted them for years on the Central Ca. coast. Mostly still hunting. Thick vegitation in hot weather.And tons of poison oak. I've just about stepped on them when they are holding. And I've had them completely dissappear in open grass. I also hunted hunted Mulies in the thick mid-elevations to the real high country of the Sierras. And in UT,now NM. These NM mulies are hard to find where I live,they are few and far between.
