I've only been hanging for a season and a half and am located North of you on the Central Coast. Most of my camping is on Crown Land but I have hung in three provincial parks/campsites and not had any problems.
With your Hex fly and SS you should be set for summer and fine for spring/fall with some care - protected and warm. The undercover will help to keep the wind from cutting through, something I find that really robs the heat.
There are several HF members from the LML who could give you more specific information. Get out and get some experience, it is a steep learning curve but lots of fun......and watch out for the bears
