Hi John,

Very interesting site!  BEE-Lers will do well to bookmark it.  It appears
Flagstaff in not that much different that the tundra north of Albany, NY.  I
hope Murry's point about latitude being a limiting factor holds water.  It
will be interesting to see how the AHB migration plays out.

Sincerely,
Aaron Morris
