I think the combat fishing needs to be looked at more as a social event rather than a fishing one. If you land a few fish, and you probably will, so much the better. Make sure you wear protective gear, wrap around safety glasses to protect from flying sinkers, hats and jackets to protect from the hooks flying through the air at times, etc.
When living in Alaska, we owned a river front lot on the Kenai River just upstream from Soldotna but I still would go to the Russian combat event for a day or so most years. I met up with a guy from Germany that came over yearly to combat fish, we got together for 5 or 6 years to socialize. Only time of the year we saw each other.
A good source of fishing info is
www.alaskaoutdoorjournal.com many of the historic fish runs are listed. Skip that idea as it appears they have gone out of business. No reason given as to why.
