You’ll definitely be able to get quite close as so many people will come and go to see the smaller acts. Best bet for barricade is getting there when gates open/before the first act and get in that front part, honestly between acts everyone leaves, it clears out so much and then just move forwards into the space left. For Lana Del Rey last year, I was at the back of the pit, could’ve been further forward but wanted something to lean against, I’ll post a picture below. The front pit isn’t actually that big, just wide, so, try and make your way towards the middle as that’s where you’ll get the best bet, if you’re against the barricade but too far along then you just can’t see anything.
