Years ago when I had that "I should be doing that too" moment was after talking with a guy riding what may have been a Rivendale. He was wearing a "Hawaiian" shirt, a straw hat and baggy shorts on a really hot day. He looked about as comfortable as a somewhat hungover/dehydrated guy slowly riding the trail back to Madison from Milwaukee on a hot summer day. He said he'd done the ride many times before and it wasn't a big deal to him, and I'm surprised I haven't seen more people wearing those.
