Tablecloth

So me and 3 friends were wandering in the Zelenogorsk area with no morphine (you can see where this is going). My friend got hit by a zombie and broke his leg. We checked the nearby areas for some morphine, but no luck. We're at least 30 minutes from the Cherno hospital if we sprint. We're not entirely sure what to do at the moment. We have decent weapons (one AK and 3 Enfields), but we are quite a ways from any medical supplies. Any suggestions on what to do?
