With the exception of the small Red Jimmie, I can get the other three about any day of the week from my house. I am just a little concerned about how excited my neighbors will be when a shotgun fires and a squirrel drops in their yard. I might have to use the air rifle to keep the noise down.
As a side note, the first black squirrel I ever saw was in Canada when I went there fishing in the late 60s. Now they are pretty common everywhere around here.
