Hay!!!!!

No really..... Hay! It's hay day! I want to join the "ton" club, but I just don't have any where to put it! Sooooo I'm off to buy by the bale and it ain't cheap! You would think that living in Oregon with all the rain and stuff, that we would have lots of cheap hay, especially grass hay, coming out of our ears. BUT.... grass hay at the feed store is almost $18 a bale!!!!!!!!!!!!!!!!! I buy from a dairy farmer and it's still $12 a bale (and not that great IMO) I'm really frustrated by this, when my filly has good hay, I am a happy girl and when she doesn't I am a grumpy girl. When I find good quality hay I want to buy in bulk so I know she is going to get good quality hay for 6mo at a time or longer. As it stands now I can buy for a week at a time, maybe two and the quality varies so much that I want to scream! I guess I need to work on my hay "networking" so maybe I can find that "golden" supplier to keep us "on the up" all year round! Good quality forage is an important issue for most horse owners and I'd love to hear from people around the country. What do you pay for hay per bale? Per Ton? What type of hay is available to you and what are the differences in prices? If your horses are on pasture, do you need to suppliment with hay?
Also regionally what do you feed? When I lived in California I fed a 50/50 Alfalfa/Oat hay mix to my QH gelding and Mustang filly. Here in Oregon I've fed grass hay only (with strategy and supplements) Our horses count on us for what they eat and I feel I've done a pretty good job when my filly cleans up at her feedings,but when she doesn't, it's on to another hay search!
