I’ll start by plugging Harvard’s free courses catalog as well as Udemy
Edit: Gonna add 2 more I remembered-
Blender - I wish I had more time to learn it, but I did start the infamous “Donut Tutorial” once!
Watch Cartoons Online - Lots of good older stuff!
I live in the Philly area. Senior citizens can use SEPTA (buses and commuter trains) for $1 a ride.
I second the biking … but that shit ain’t free. Even used bikes cost some money to buy and maintain, and brand new bicycles are solidly in the “insane” category these days.
Good point — it is “incrementally free,” although I guess if you count tire wear and tear that’s not even true.
