Winter CSA

I was curious if anyone has a share with a winter CSA?
Do you have any details or thoughts about the value of it?  I find that my food bill goes
up and my diet seems to change in the winter to reflect the cold weather.

I tried doing a CSA while living in Salida, CO and I must say I was rather disappointed in what was given every week vs. the cost.  I think it is a good idea, and with more info and knowing if the CSA provider was established at growing would be helpful.
