Going to snowy Lake Tahoe (Next to Nevada) for the weekend

Yep, I'll be going to snowy Lake Tahoe (which is on the border to Nevada & California) for the weekend. Three nights at a resort kinda in trade to listen to a timeshare seminar thingie. Oh well. It's about a 4 hour drive. Halfway is Sacramento. If it's snowing, it will take longer of course. And by all counts, it looks like it'll snow. I have only seen real snow fall 3 or 4 times in my life: Tahoe and Michigan. Barely snow on the ground when I visited New York and Philly. We will be leaving early in the morning tomorrow. Hopefully it'll be an easy drive and not too freezing. BTW, I hate long drives. Ugh.
