I have a 16x16 scarecrow available for sale in Solzreed near Wardton. It is conveniently located near a ramp to the water. It's handy to have, although I never farm there. I also never seem to run packs off of it, so it is not as useful for me as it would be for someone else.

PM or mail me in-game (Character Name: Ayumu) with offers, I'll sell it as just the spot or sell the scarecrow with it!
