Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
they do put sweepers out there, mine extend out about 2-3", but they do very little damage from my experience. i have duncans right near mine as they have each grown and no issues - and these duncans close/run and hide when i sneeze too loud!
