i am 25 now and i was at cascade school in whitemore, ca when i was 14-16. i did graduate cascade and I believe i was in "middle school" or "upper school" cascade school level when paris "moved in". I helped her move in and I remember that the levi 501 jeans we were forced to wear, didnt look like levi 501s on her cuz she was drop dead hot. also i remember she had tattoo's makeup, like eyeliner on and it was a bit of a drama amongst jealous other girls at the school. paris was very nice. she ran away with another girl. i forget her name, but that girl she ran away with came back to the school and i became pretty good friends with her. she told me what they did when they ran away, where they went and what they did. made me vow not to tell, and to this day I will not tell (except i did tell my hubby!).
but yes, paris hilton went to cascade school for a brief period of time before she left. maybe she went to other "theraputic boarding schools" too, i dunno. but i know she did go to cascade. and in my opinion, she NEVER belonged there.
