Last frost date in Davis?

[genevra-mcneil.livejournal.com]

After years on various waiting lists, I have finally gotten a plot at one of the community gardens! Now, as a complete gardening newbie, I was surprised when all the instructions about on the seed packets I bought (and bought and bought... maybe I got a little carried away?) talk about the "last frost date for my area". I have to be able to predict the future to garden? Zone maps were unhelpfully general.

I called my FIL, an expert gardener, who said that the difference between his place in Conn. and mine in Boston was sufficiently large that I needed to talk to local experts. You all are my experts on local so.... when's the last frost for Davis (as a general rule?). 

Thanks

my parents are both avid gardeners in chelmsford, which is about 5 degrees colder than somerville on average, and they have always abided by the memorial day rule for 20+ years and it has never failed them. we've had some frosts mid-late may, i remember. no fun having to run out and cover everything =/
