Well, tonight was "ride a motorcycle for the first time" night for my wife. We didn't head out until dusk, so she didn't get much scenery, and the bug splatter increases by a factor of about 100 once it's dark out. But she gave it a shot and had a lot of fun.
It is pretty clear that I'll need to replace the stock seat on my Beemer if I want to get her to come along on anything longer. Maybe a custom seat from Sargent with a stealth backrest. I'm sure my wife would enjoy having something more than open air behind her but while we're cruising around. If I can get the seat before Labor Day, I might be able to convince her to cruise down to Hatteras and Ocracoke Islands for a weekend after the tourists start to clear out.
