Went out to do something in the yeard this afternoon and found this nest on the fence rail ...

For these wasps ... this nest is huge! They are usually about 1/4 of that size.
The wasps themselves are about 17-18mm (3/4 inch) long I guess. They are fairly docile unless you actually brush up against them.
