Where are the winery websites?

I have been doing some internet research to see what is new with some of the wineries we are going to visit on our short trip to the south Okanagan this June. I have been disappointed by a couple of websites which don't appear to have been updated for at least two years. It seems amazing to me that this part of a winery's marketing would fall flat, especially when sales can be made online!

Why not update seasonally if you aren't able to keep current? Is it a lack of web support? At least update the site at the beginning of the season, when tourists are gearing up for their holidays and doing their planning!
