Right??!! So agree! Enough already. Hard to be a beach bum with all this madness. I long for 90 to 100 degree heat!! Looove it.

The Rain in NorCal

Is such a drag!!! Gotta get our Sundance mojo going! This is too much! Makes me miss LA.

It never rains in the Bay Area in April

If it keeps raining in the Bay Area through April I am going to lose my mind. We have had nearly constant rain storms since mid-October. I really hope this forecast is wrong.

Frisco rain

I hope it continues to rain through June!!!

Rain in california

Only people from SD get this, right!?
