My current view.
These were the halcyon days for cycling: before cell/smartphones and their distractions; before elevated levels of driver rage and aggression. I still miss downtube shifters.
We used to pull Malt-nut Powerbars from their foil wrappers and wrap ‘em around the top tube (for more convenient eating).

I don’t know that I ever saw someone wearing a bicycle helmet except on TV. Bell didn’t even start making helmets in kids sizes until I was a sophomore in high school.

Not a superb photo, but this is definitely a superb owl - a great* one, even!
Logan and I passed within 2 m (~6’) of this gorgeous creature while walking a path along the boreal forest edge; I took this photo after putting a bit more distance between us. Logan didn’t notice it, fortunately.

5 years ago today a massive debris flow raced down the Ronti Gad, Rishiganga, & Dhauliganga valleys in the Chamoli region of Uttarakhand, India, destroying two hydropower plants, and killing around 200 people. It was a horrific tragedy and my thoughts today are with the families of those killed 🧪⚒️

Sir Ian McKellen performing a monologue from Shakespeare’s Sir Thomas More on the Stephen Colbert show. Never have I heard this monologue performed with such a keen sense of prescience. Nor have I ever been in this exact historical moment.TY Sir Ian, for reaching us once again.

I’ve just finished a lab exercise with my environmental instrumentation class, in which we built an automated weather station on the top of a 15-story building here on campus.
About half-way through, I noticed that we had company: a merlin!
It seemed completely unfazed by our presence.

My rear fender was laughably undersized for my fatbike’s 4.5” wide tire, and the warm spell we’re experiencing here in Edmonton is melting a lot of snow and ice.
My low-budget solution worked a treat this morning - I arrived at work with a dry backside.
