I should go to public spaces to draw portraits

-Have gotten decently ok-ish at drawing from observation and can usually get a decent impression of scene done
-Improved at drawing portraits of people too, and even self-portraits have been more interesting
-Confidence and more practice makes one better at portraits, but limited opportunity to do portraits, no models
-If I went to public parks, coffee shops, other public spaces, I'd be getting free models, improve portraits
-Interacting with subjects would be an interesting skill to learn too, legit thing worth improving!
