How early are people lining up for shows?

UPDATE: I ended up arrive just before 1pm and was first in line for just regular GA tickets (no early entry or soundcheck). By the time I was allowed into the venue I managed to snag a spot 3 rows back from barricade

Hey everyone, I’m hoping to get a spot close to barricade tomorrow in Seattle and wondering what time people have been lining up these days? It’s been a while since I’ve been to a show so I don’t have a frame of reference anymore. I’m driving down from Canada so I want to make sure I leave early enough. Thanks!
