Whew! Now I know: I am only semi-crazy ;)

Wanted to say thanks again for all of this. I think I'm going to risk a cab downtown, since I'll be arriving mid-afternoon and since SAB advised that street closures should not affect me the way they would here in NYC. I appreciate the advice!

Have a fun time in SF mattydale, and I will keep my fingers crossed there is not fog on the 4th!!
