Replying to Back to skiing after ACL surgery

I was talking with my physical therpist today about skiing. So i started asking him about what he thought i'd be able to do. he thought i should take it easy for most of the season and kinda stay away from the park. He said he doesnt know much about the park and that whole deal. he said to check online and i thought duhh newschoolers.
I had surgery april 2 (my birthday!!) its been just over 4 months now.

I dont really know how soon i should start pushing myself and trying new tricks. should i jump right in and pick up from where i left off or would it be to risky.
Anyone who has torn their acl tell me how it was like when you got back to park?
