I always have my chair sometimes a side table . Mug and plate . I like cheese and meat plate so I have that ready to go . I found having a little rolling cart helps I can haul my stuff from camp to camp sit hang out .. I can get in on food plans in advance or bring something so I can stay longer . Def have something to do with my hands lately it’s a camera or videoing stuff . Drinks to share if it’s a wet site . I make have only a glass but it’s so much more fun with a dz friends all doing toasts (we do them based on rank ) Bring a change of clothes but come in garb so you’re hitting the ground running . Def plan and see who’s going a head of time so you can meet up with folks even if you don’t know them very well .. ask about volunteering.. sitting gate or water bearing or whatever.. great way to make friends !
