oh thats the infamous quad kink at alpine!!!  i was thinking 50 feet of pure adrenaline pumpin kinkness the way its been described.
ill sum up all the private parks because im a member at one:
Osler: Osler really stepped up there park this year.  it finally got a table that was 35 ft. and worth hitting and was kinda fun.  got good air off of it.  near the end of the year we got a nice little rail line set up with a small box, down box or small flat down rail, then a 20 ft. straight rail or really really fun flat down flat rail.  that is all we really have.  it then goes to a little butter jump that was fun to just play around on.  then our stupidly small gay ass pipe that sucked complete fucking dick.  then a shitty table that hurt but was good.  it had two options of bigness so pretty cool.  then an up box which is fun to just hit then 180 out of it.  thats the park
Beaver: this is a pretty fucking sick park.  it could be amazing but still lots of fun.  it starts off with either a jump line with really gay table/kicker jumps or a rail line with a kinda rainbow-down rail combo thing then a steep flat down rail or a hip, to a down rail.  the jump line was about a 15ft, 20 ft, 20ft, then a really fun jump that was probably 30ft.  beside the 30 footer was a nice 20ft. flat rail which was nice and smooth.  this went to a little freestyle area jump which they hold the comps on to a flat down box (fun) or a triple picnic bench combo which was super super sketchy shit.  they tried to make a quarter because they dont have a pipe (yet getting one in 2 seasons for sure) and this thing was an uphill to wall thing that was stupid.  but it was a good attempt none the less.  they had a super mellow flat box which was super good to do whatever you wanted onto and off.  thats the end of that park and it was pretty sick.  for sure check it out.
Georgian Peaks: this park hac the potential to be good but not a long enough run to be really worth checking out or anything.  the park is loaded with boxes.  i cant tell you the exact layout but ill tell ya what they got.  a flat down flat box and a down flat down box.  rainbow box, straight box, 15 ft. high rail, three jumps from 10 ft, 15ft, 20ft.  Then a wallride which was lots of fun to just go up and stall or a super sketch c box.  still fun.  so thats all the features i think.  only went there once so not super sure on the features.  Then they have a pipe but its like oslers.  super small and kinda sketch.  fun for a little run of stalls and stuff but no blue pipe.
ya so thats all the private parks i know about hope it gave you a good idea of them
