Ummmm Rattlesnake. Ten minutes into the trail. It was a warm day of 86 but I was absolutely unprepared for such things!! Do be careful. She was laid across the trail so I heeded her kind warning and headed back with a quickness to the vehicle. Where I'm from....the State/County/City typically posts a warning of: Bobcat, mountain lion, whatever might be in the area. No rattlesnake warning in sight but now I know...and now you do too..!
