I love that the area of a parabolic arch is 2/3 of base times height. It's so simple.

Nice 40K bike ride the other day, a quick burn around the pathways near Rama 2. 

Stand! Shout for Blue in 2026! 💙💙

I love this painting! Happy Birthday former POTUS Barack Obama! You’re 65 today! Dig that tan suit!

I don't get airbnb. I've stayed in a handful and they have always been more expensive, unpredictable and less reliable than getting a normal hotel. That's not even taking into account the corrosive effect they have on local economies.
