I live in Central PA. Rossman is sending out my packages around April 28. From what it seems, not only do they go by climate zone when shipping, but also first come first served. Personally, I wouldn't be happy about having to wait until Mid-May. I don't even like having to wait until early May. The majority of the best flows are winding down by that time. April is a good time IMO. What can you do though. :-\ Call and complain but I doubt it'll do any good.
