Busted,
Most people are friendly enough to chat it up, especially if you are talkin' fishing. Just ask them what they are fishing for and how they've been doing. You'll see what they are using (and how) on their next cast. Please be sure to get familiar with the WDFW fishing regulations. They are confusing but you WILL need to know what is open and what isn't. Spend plenty of time in advance to know not only what is open but what gear is allowed at different times. The rivers are usually divided up by sections so definitely don't assume that just because one thing is allowed on the lower portion of the river that the same rules apply 10 miles upstream.
