I feel your pain. Guys do not respect anyones water anymore. It has become such a problem that i think guys think that its the norm and start doing it themselves.
My partner and i always try and respect someones water. We always offer to go around a on coming boat first or move to the opposite bank.
Keep treating people right and everything will work out. Don't let them effect your mind set because it will only bring you down mentally. This will cause you to lose fish and miss the money.
Good luck this summer and thanks for the post.
