Hi @OldNoob81and welcome to forum. You will find lots of practical advice here.
Main thing is to make sure you have some good eye pro and sturdy footwear.try and make sure most of your skin is covered. You probably will go home with wealts and lumps!we all have! Lol.
Start out early on the 4th so that you have plenty of time to look around and get organised.sort your gear the night before so that it's all ready to sling in jam jar,do a little check to make sure you have all you need.
When you get to site and see all of us nuts in full battle dress with multiple weapons strapped to every limb,don't feel underdressed and keep in mind that all of us started somewhere. Ask questions, aitsofters love to talk! You will probably be hit with more advice than bb's lol.
Listen up to any instructions from staff and watch what others are doing.
Its an easy learning process really,the hard part is funding it!lol
Have fun and let us know how you get on.๐
Ps check out @GAMBLEhe has a tube channel that is worth ๐watching.
Regards
