What if we dont have any bunkers either though? :/
If you don't have sup air bunkers on a site you will most likely have a form of speedball field - hyperball, wooden bunkers etc
Take cover and snapshoot around whatever the obstacles are
If you need to then get some pallets and prop them up
Practice the core skills around hard cover, this will be more difficult and slower, particularly when it's dodgy or not possible to run, dive and slide on uneven ground and hard objects
Then when you are around inflatables you can get straight in
If you need more practice leaning into inflatables then get a laybag, stand it up on its end against a bunker and practice your position
Do dives and slides on good ground which could be at your local park etc
People may look at you, but at least you won't look as stupid as a Lycra jogger
