One encounters lots of interesting things while riding the bike.  For example, I saw two deer at 106th and Hazel Dell on Sunday, but they weren’t the usual does or young bucks–these were big guys with eight-point antlers.  Neato!

Lots of these sights pass without comment.  Another blue heron!  A Ferrari!  A racing rival riding the other direction!  But every once in a while, there’s something worth stopping and recording for posterity:

Rolling south of Bloomington.
This caught my eye because of its relation to my friend and BGI mechanic JB Musselman (whose name itself is also hilarious for obvious reasons).  So I stopped and snapped it for him. 

Also of interest was the following gem that requires a little explanation.  Around these parts, the accepted method of informal bike route marking is known as a "Dan Henry:"

Rest in peace, Dan.
You find these all over the roads around here.  They’re generally very helpful, except when routes intersect, and then it can be a little difficult to make sure you’re on the one you want.  It is also easy to confuse with another common symbol: 

Luckily, this confusion only occurs at specific types of intersections.

You also find the occasional attempt to introduce a higher level of artistry to the Dan Henry:

Scenic Route.
The white symbol above is not uncommon, and it has the same role as a Dan Henry, except more specific:  if you have a bike with two disc wheels, and a transparent frame, then you want to go this way.  Also:  no helmets allowed.

The yellow symbol is far less common, for obvious reasons:  most robots don’t bother with a bike route, since they have other means of propulsion.  Unfortunately, the artist left their message a little unclear.  Does this mean "robots go this way?"  "Danger:  Robots ahead?"  "This route only for cyclists with a robot sidekick?"  I lean toward that last explanation, since a cyclist with an invisible bike frame would probably also have access to robot technology.
