Bison-ten-yell day? Which, despite being a moderately 

clever play on words isn't clear about what it is or how 

one would go about celebrating it. 

So I went for a little father-daughter bonding time. The old catch in the backyard. We were running low on light by that point and I was distracted by the bats that kept crookedly flying through my line of vision but it was a good time. In fact, maybe that ambiance enhanced our experience of shoptalk about libraries and Field of Dreams.
