Boy, you get around, don't you?
I have some good news, some bad news and some extremely interesting factoids for you:
The bad news:
I know little about the enormous square mileage of the Metro region in which you like to recline with your pals and moisten your rods, but I am sure that a number of OFF members that live up there will happily give you a hand.
Factoid:
While working on my Masters Degree in Asiatic Studies with a minor in Political Conflicts and Their Relation to Primate Habitat (formerly King Kong Meets The Vietcong), I wrote my thesis on "public seating in Oregon parks (See: Long Hard Wood and Latex; A Guide for Lumber and Plastic Bench Fanciers)".
Good news:
My thesis statement classified public seating by venue type (in this case municipal parks) and then lists the number of benches within each venue. The park with the most benches in Oregon? That would be Furnberg Municipal Park, located at the corner of 70th Avenue and Furnberg Road, Milwaukie, Oregon!
Bad news:
South end of Milwaukie.
Good news:
I am an avid reader, especially fond of any text that could help increase my dismal fishing skills. I had to laugh when I saw your thought about waterway duck-feeding and how you feel that this occurrence improves one's catch rate.
Factoid:
Not at you, with you.
Additional news of a positive sort:
Not two days ago I finished a very interesting tome titled, "Thar He Blows; Angling and Perversion In Our Scenic Waterway Parks", a collection of articles, tables and statistics relating to waterway angling and watersports (not to be confused with "water sports", chapter 4). This book is sort of an angler's almanac of ways to improve your catch rate and it is brimming (not to be confused with "rimming", chapter 3) with ways to just be sucking them in.
Another Factoid? Well why not?
"Thar He Blows" actually has a table within that gives a breakdown of expected increase of catch rate, based on feeding/chumming on or near a water way with these variables considered: The species of animal being fed or being chopped and pulverized into a liquatios goo for chum; the type of feed used and; the geographic location or structure type where the feeding/chumming takes place. Since I don't know if I can insert a table into a thread I will list some of what I thought were the more interesting bits of data.
First, let us look at your scenario in which you state that shoreline bench-related Mallard duck feeding of Bread, White (stale) improves your luck- Answer: Correct! As you so brightly presupposed, the table shows an average catch rate increase of 23%, leading me to wonder if you have already read this book or if you are just damn smart. Good job, regardless!
Some bad news:
Another factoid ahead.
Factoid:
Here are some of the more interesting tidbits from the afore mentioned table:
Squirrel grey feeding of nuts, filbert at waterway bench. Catch improvement 35%
Cat feral feeding of tuna left-over, salad at top of improved waterway boat ramp. Catch improvement 9.6%.
Rodent rat, large (or possibly Canis familliaris, Chihuahua) feeding of Jim, Slim behind waterway toilet enclosure 53 feet from waterway. Catch improvement (-100%)
Chum type Pony, Shetland liquatios goo particle size .47cm at shoreline (lake/pond/slow river). Catch improvement 72 %.*
Note: Chum application River fast-flowing. Catch improvement 68% at 479ft downstream.
Good news:
I think we are finished here.
Bad news:
I am going back out to garage for a few hours where I will be able to think of other books that I have read that may be pertinent to this discussion.
Factoid:
I typed this whole thing with one finger on stupid iPad screen keyboard.
