Memorial weekend winery tours ( Yamhill County )

[sweetirish]

I'm planning on venturing out to Yamhill County ( Oregon ) next weekend and doing some
winery tours. I gather from the local papers that Memorial weekend is a big event at all the wineries but would like some imput from some of you that may have some experience with wineries in the area. Which ones are the best to go to?? Since time is limited, I would rather hit the best places...

Thanks for anything you can tell me!=-)

PS...went out today to Rex Hill and really liked it...=-)
