There's no doubt that Oakmont is a great golf course, but it's one of the few courses that I've played where a big miss off the tee is normally left with an open look for the approach. It might not be a good angle, but it'll be open in many cases. Whereas, a miss just off the fairway many times will result in a thick lie or having to play out of a very deep bunker.
What other courses have you played that are similar? In my travels, I can't think of many.
So many inland courses are treelined, treelined not just clumps and copses but treelined all the way in continuous avenues alongside fairways. A normally accurate player who misses the fairway by only a few feet will get punished with a slightly off-line shot, mostly to the value of a shot (chip-out time), whereas an inaccurate long hitting smash-n-bash type aggressive player can be over the trees and on an adjacent fairway.
I'm not keen on courses like this. Trees in clumps and copses are IMO much more preferable to long continuous avenues. More creative opportunities for shotmaking, better quality grass, more air flow, quicker drying, less tree maintenance, leaves blow away easier in the autumn etc etc. Fairer too, as a more 'open' course with not much in the way of tree avenues plays more equal for all, especially if there's limited or low cut rough alongside the fairways. This is one of the reasons I'm in favour of courses like Minch' Old, the cattle and horses course, not that I'm comparing it with Oakmont though, but I'm sure you get my drift.
One other aspect of treelined courses is safety. Trees are sometimes placed to avoid players being hit by a ball played from another hole, ie the assumption being that the ball will hit the trees. But, if a shot is hit over the trees folk frequently don't shout "Fore" because they can't see anyone on the other hole. If there were no trees, the player/partner of the wayward shot could actually see the other hole and if people were were there could shout the usual warning. Hit, look and shout "Fore" rather than hit and hear "Ouch" , followed a few minutes later by "Sorry mate, didn't see you there". I've seen this occur a few (painful) times.
As to a famous courses, although it's obviously not an inlander, but if your misses go left, TOC could perhaps qualify in relation to Jonathan's original post.
All the best.
