Suggestions for first timer?

Gold Bond. Lots of Gold Bond.

We bring coolers with food and beer all iced down before hand. Easy-up for shade, tarps/tapi's. I bring my bike so I can cover more ground and really explore Lockn it's a blast! Security is fairly lax long as you use common sense...we bring a container of ground coffee even though non of us drink coffee in the morning... Sure you can put 2&2 together....Vape pens you can just put in your pocket, they aren't worried about those, mainly looking for weapons etc..

As stated above you'll be walking or riding a lot so baby powder is essential to stay dry. Also get pedialyte packets...these will save you from a bad hangover....will bring you back from 0-80 by 11am!

See ya on the farm, your gonna have a blast!!

For GA, jiffy johns and a "few" pay showers. I bought some shower wipe packs online and glad I did. Powder.

Case of beer in aluminum ok (read online details) or wine in a box (or can), NO GLASS, no weapons obviously. Alcohol for the campsite, not to bring in the venue. Plenty of food, beer, coffee, and fruit smoothies available to buy in venue. Free water filling in venue. I brought a bike to ride around the outside, but no real need for the daily trip to the venue, unless you need to go back and forth a lot. They advertised places to lock bikes at the venue gates, but I don't think I saw those at the back entrance. Wouldn't know myself about security either way, but I saw plenty of recreation. They do sell ice, but that is high on my list, to bring ice. 4 days is a long time, don't get sunburn early, so sunscreen from the start. Shade in the venue is very limited and music continuous, so build a plan for that (hat, kerchief, sunscreen, chairs in the back, etc., etc.). Night can get cold late night shows (or not). Earplug option if needed. Gatorade or the electrolyte pack mentioned (those are cool, have to find those to buy).

Can load a charge card link onto the wrist band chip for food/beer/swag purchases in venue, but cash just in case. A few general store tents are outside the venue in the camping areas, with essentials. I found ice easily when needed. No lockers inside venue last year. Hope they have them this year.

For bottles into the venue, empty bottles (and I think a sealed water bottle full maybe ok, I forget).  Free water refills inside venue.

Silly grin to last 4 days. Your Dead apparel. Cheers!

True dat.

Also bring warm stuff.  It can get pretty chilly at times in the forest at night, even when it is toasty all day.  It's damp there as well, depending on when it last rained. But, hey - it's a freakin' forest!
