Your wife sounds a lot like mine. Just take us along on your vacations and she'll do the museums and buildings with her while you and I ride.

Seriously, though, I have always left the bike at home when going on our annual vacation with her, but I almost always find myself on at least one road thinking "It would be really fun to ride here". She suggested I ride one day out of the week, but that's hardy worth the trouble of packing the bike and equipment.
