Hey, heading from Vegas to Sonoma for a week at the end of the month. I've stumbled upon "Wine Road" http://www.wineroad.com/ , which is, among several other things a Ticket you buy for 1 or 3 days that gets you free tastings in around 80 wineries, plus discounts on wine/merchandise. It's a steal at around $25/$50 respectively. Many of the wineries were ones on my 'hit list" already.
Does anyone have any experience with this? It looks too good to be true.
