Why not grab a friend and go on an adventure around town on your day off? It’s fairly inexpensive if you utilize public transportation and the things you discover about your city could be invaluable. Just hop on the bus or rail system and go. Get off one bus and transfer to another every so often. Worst that can happen is you end up on a bus somewhere on the other side of town. Best thing that can happen is you and your friend find a new lunch spot that you can call your favorite or a park that you were previously unaware of. It really doesn’t take much but $5 and taking a step out on a limb. Why not?
