thank you for the correction.

Do your tires say M+S on the side? if so you can drive up legally.

if you don't feel comfortable doing it, don't

end of disussion

Many people are overconfident based on the degree of experience they have and level to which the vehicle is prepared, so sometimes that comfort level needs a bit of outside input.

Not end of discussion.

Have you ever driven a Gen coupe to whistler in a snow storm?

No, but I've driven other RWD vehicles through snow storms to Whistler, and a Gen coupe doesn't have especially unique handling or power characteristics.

Roads are clear, just got back.

edit: burned almost an entire tank of gas getting to and from pomo-whis.

To the OP, you can't gain experience with your RWD ride in the snow unless you are really in the situation... so take your car and take care. It should be fine.

My suggestion:
1. If you are really paranoid, look over the map/ streetview on Google when you have time. Try to visualize the tricky parts. There are a few turns that can creep up on you.
2. Check the weather report the morning / you are about to leave or even at the McD on the way while breakfast eg Squamish. Weather report in our area get better prediction only for about 12-24hours.
3. Check the highway cameras (despite what others might say, it gives you more information ahead of time).
4. Do all the basic preparations: tires' pressure, windshield fluid (important).. top it up or maybe have a spare can (of that), brush etc.
5. Don't drive like an idiot... drive at the speed you are comfortable with and let other people pass if they are pressuring you. In an RWD, You will only get into trouble when you change your weight / momentum around eg hard braking, so reduce your chances of that you should be okay.
6. Be prepared to be turn back if things really go to crap (I doubt it)... don't pressure yourself to hurry.
7. When you get to Whistler / surrounding area.. find a empty parking lot to practise / get the feel of hard braking etc on icy surface.. (late at night is usually the best).

I drove my e36 with stock MXV4 tires up and down Sea to Sky close to 20 years ago every weekend.. no traction control, no nothing.. Go easy on your gas and brake, and just build on your experience. The only trouble I had, was at Cypress at the final hairpin which I forgot, car spun around into the snow filled ditch.. waiting for the tow truck and bruised ego was the result.

That's almost as much work as I put in when I go for a flight... Over analyze a bit maybe?

I am not sure I want to fly in your plane, if your checklist is this short.. most of those things are pretty common, check weather report etc? Since the OP is worried enough to post on the board, using a checklist will help him make sure he got everything covered and build confidence.

I thought we require the following:

It's kind of complicated I guess.

Checklist = walk around, weather, flight plan, notams, don't crash. That's preeeeeeeetty much the same for any plane.

if you cant drive up the sea to sky these days because you are scared/worried, you shouldnt be on the road period

i usually use chains when i use that highway
