I am in SE Indiana and have a few that will be at a year drying in April. I'll give you one if you happen to get down this way. All of mine are 72" since I usually make a 70" bow for myself.
If you buy online be very mindful of the preparation and drying process. I have seen two people get burned the last few weeks buying staves online that were not prepared properly and cracked through the rings making them useless for a bow.
