Tim that is unfortunate, pisses me off and I wasn't even there.
I would have loudly voiced my opinion.(I know people who have had their trailer tires slashed for lesser evils on the West End. Just because they own a jetboat or low hole a guide). The boat should either move downstream or come to the bank. I have fished with guides that actually practice "leaving fishing spots alone when bankies are present". Boats can fish from the other side or become bankies with you. Not all guides practice this ettiquette. Do you know this guides name? He owes you an apology or at the very least his side of the story!!
