I'm wondering on how you unlock the race track at Lara's House. I pressed the switch on the diving board where the pool is. I pulled down that lever where I have to dash across to that museum. I pulled that secret book switch (I forget what that does). I have got to the race track before, but I cannot figure out where the key is to unlock that gate. The attic place in the house, there is a block that I can push or pull. If I push it in all the way, I can't get anywhere. If I pull it out all the way, I would still have to pull it back one more time to get through that way. I think there is another way to get in that room. Please help me ASAP. Thanks.
