road trip to dad`s

Spent a short two days helping my Dad around his house in the Sierra`s. Fun but kind of emotional weekend, as he gets older it`s hard for him to keep the house and yard maintained and I wonder about his driving, how much longer can he live alone up there? what happens when his dogs pass? (they are 15 & 16 yrs respectively)He knows he can live with us but Orange County just doesn`t suit him anymore.It`s sad but a normal part of life that I`ll just have to work through. One day my kids will be asking the same questions about me.
