A week after my first blackberry picking handful, I went back wearing long sleeves, long pants, and knee high boots. I returned with three cups of berries.
This is what it looked like a few hours later.
A week after that I went back and picked all I could find, and now I have two pies' worth in the freezer.
This year's growth is prolific. Next year should be a good one, weather permitting. Last year, there weren't as many berries, and the ones I tasted were so bitter I didn't pick any more. The different combination of heat and rain this year must have made the difference.
