Get used to it, the vedder/chilliwack is classic for walking in on somebody fishing the run thru. Lots of new fishermen, or just plain ignorance. That being said, the river belongs to everyone, I will ask nicely if I can fish thru, nobody has ever said no. If a fish is caught, congrats! That is what it is about right? I think it is exiting to see somebody else get one, because where there is one...there are usually 2...3...etc. Oh and alot of time where that fish is hit...they will be there next time, so make the note, and you will catch fish there again, and again...etc. Or I will anyways, mad skills and all.
