In which Emily chases a bobcat and I hunt for a mountain lion and we all get thwarted by private property! Originally hoped to do a loop, taking Alum Rock Falls Rd. to Mt. Hamilton Rd. And Joseph D. Grant but the two ways we tried were fenced off with some pretty official signage. The second one, when we tried to take the road instead of the trail, was for sure very legit with multiple signs for Blue Oak Reserve - UC Berkeley. I thought the road went passed Blue Oak rather than being contained inside it. The trail route that we tried first in Sierra Vista was VERY steep and muddy. I managed to get up it without sliding but Tony and Emily weren’t so lucky and had to hike several sections of it. It was sort of worth it for the nice picnic spot at the top where we had lunch. At the top, there was a bobcat that Emily tried to get close to. Earlier, a hiker warned us of a mountain lion and we ended up doing a different trail to avoid it. Once again, today was warmer than expected. An all around gorgeous day (in which I forgot to start the timer because I was busy worrying about getting the navigation going).
