what zone am I in?
I just moved to northern Delaware, just a few miles south of the PA border. I've checked the USNA website (http://www.usna.usda.gov/Hardzone/hzm-ne1.html) to see what zone I'm in and it looks as if it's 7a but it's a little hard to tell. Also, it seems on this map as though the zones change with the state lines (PA, NJ, etc.). Can anyone tell me for sure?
