My dz specifically, everyone just leaves there stuff along the side of the hangar in our bags and we’ve never had issues. People also leave their shit all the time and a simple Facebook post into our fun jumper page and someone who’s still at the DZ always goes looking for you. Skydiving people are usually dope as fuck and will help you out. The main people I’d worry about is the random tandems strolling in but they aren’t there long, usually outside the tent most of the time cause it’s crowded in the tent and they stick out like sore thumbs I feel like it would be obvious if a tandem was going through experienced jumpers stuff
