Traffic

So I've always used Sigalert to find out how the traffic's like before I head somewhere, but the problem with it is that it's only live. So there are times when I want to find out if a particular section of say 280 will be bad on my way home from a work meeting and whether or not I should take a local route, but was never able to figure it out (unless I had the foresight to check the site a day or two early!). Just today, I decided to try the traffic indicator on Google Maps and it's so cool! You can have it predict traffic on certain days of the week & at certain times!! I love it! And now I know that it would be a VERY bad idea to take 101S to dinner tonight. =P
