Could i get friends by talking to strangers on the street? Or will it be weird?

I've decided to make more friends since i've boosted my social confidence. I don't have a problem if a few just reject me but my problem is to know if it generally is something i should not do because it might be weird but i don't have any other environment other than school to make friends. I know the basic stuff, i shouldn't bother people who are busy, or look tired or whatever but i was thinking on just walking around open enviroments like parks to find people.
