Oh, I don't live too far from here!!
And, we are also getting ready to visit the Aspen Grove - it's between Yucaipa and Big Bear, and if you visit at just the right time, you can see the incredible Aspens in their yellow splendor! A couple of years ago we didn't get there till mid-October, and the leaves had already fallen. This year I'm thinking it will be a mid-September hike
