That is the best way to hunt rain setting up along field edges!!
I went and bought me a Dog House Blind and that is what I choose to sit in on rainy days

Before that I used my camo unbrella.
The Birds don' t seem to pay any attention to either one.
Try it!
It may just keep you in the woods longer

I know that I don' t care to get soaked any more than the next person and this year I have had only 1 day to hunt that it didn' t rain so far.
