What should I explore (alone) over the weekend? Living here for 1 year now

I’m looking for ideas bc I’m bored lol.

All my friends are busy this weekend and I’ve realized besides going to work each day, I never really explored Houston.

I’m m23 and from other parts of the US. SO far I’ve been to these places: – lots of restaurants across Houston – Galveston – Katy area – space center (NASA) – s couple of museums
