Yosemite cancelled! But San Francisco here i come!

We had plan to go Yosemite this weekend for snow-shoeing for the long weekend(Monday's Martin Luther King Jr day) but it had to be cancelled coz the weather forecast predicted that it will hit a low of -4 Fahrenheit. Not advisable for 1st timers. Yes, Fahrenheit. Not celsius. After converting, it will be a whoppping -20 degrees celsius. The organiser told us to go during the next long weekend which will be Feb 17-19! Haha! Chinese New Year is a public holiday here too! But it's called President's day here. haha. Chinese New Year out in the mountains! Anyway, after some discussion we decided to go San Francisco instead! Hehe. So those of you who been there before please give some sugeestions of places to visit!Ok..off to copy my homework. No idea why the prof still wants us to hand in the homework when he released the solutions already. Just a waste of my time haha.
