How was the company at Gridlife? Never been but all the marketing makes me think overcrowded with a super wide range of skills (even within intermediate/pro) making for awkward sessions?
the cars or in general? gridlife is bigger each year and the gingerman one has music and a whole bunch of people, plus the time attack field seems bigger than ever. so hpde guys are almost all parking rando spaces in the grass, then you have clueless people walking around the paddock too, so you come off hot track with hot brakes and you'll never ever make it to your spot without using your brakes multiple times because of so many dopes. gridlife autobahn has no music and no camping, so you can park on asphalt and the paddock is much less busy.
the other negative is your track time is 4 20-min sessions, spaced pretty far apart given the extra track sessions - instructors have some, multiple drift sessions, time attack - however they will run the event past 5pm (out to 7pm)
like most events it's self-classify although i think people in general have become better at classifying themselves at gridlife events. i think a lot of regulars came from wmhm and wangfest so it is a crowd that in general has done a lot of gingerman and moves pretty quick on it.
advanced seemed pretty busy when they had combined instructor+advanced. intermediate never seemed too busy to me though and i thought passing and point bys were done well. it went pretty smoothly.
i have some friends doing gps tt sat 7/1 at gman and gridlife sun 7/2 at ab south.
gridlife ab is pretty cool, if they copy last year's schedule, saturday is a couple sessions north then the rest of the day full, and runs into the evening, which means you might get some pics of your car with glowing rotors too which is pretty tits. then sunday is all south. the time attack guys have best laps taken from each configuration and added up.
