From the AZApiaries.com site:
Well once again, I hate to be the bearer of bad news. Due to the persistent cold weather down South all package dates are now postponed by two weeks. We hope that this is the last change needed to the schedule but all customers are urged to monitor this site for more info as the dates get closer.
The West Nyack pickup date still shows April 2, but that is probably an oversight. I am sure the date is April 9, but I will verify, rather than trust.
