Thanks bsk, We've been brush hogging the 20 acres...another pest -- the wild plum thickets. We're just blessed with lots of pests! I have been picking the wild blackberries for our personal use, but hadn't thought about selling them for profit. As you know copperheads & diamond back rattlers love to call those blackberry & plum thickets "home sweet home." So that's one liability issue right there. All our trees lean to the north because of the constant wind from the south...and the grasshoppers were already hatching out in February. Living in Oklahoma (where the wind goes sweeping down the plains...) can be a real challenge! Vicki Day-Cook Oklahoma
