Yep, when she agrees to go for a ride, we both always have a good time - putzing around, running errands, breakfast runs, etc.
The only problem is she's still VERY reluctant to put our kids' parents' lives (that is - our lives) all in one risk basket like that. When our 3 kids were young, she just flat refused to ride. Before kids - we'd ride together whenever. Now that our youngest is 15, she's beginning to get a little more willing to ride together again. And when we do, we both enjoy it. But, I've always respected her reluctance and never really pushed it.
Enjoy!
