We found a few of these trees, growing along a country road. They look like citrus leaves and even the fruit looks like small oranges but the skin has a velvety texture and they smell like Passion Fruit. Sorry, I swear these photos were upright on my computer!
maybe Satsuma?
No, they're not oranges. I have a couple of Satsumas. Thanks though!

I think it may be Bitter orange, Poncirus trifoliata, the skin is fuzzy and it is used for rootstock for citrus
