Not the Hospital Hole, but farther upstream:
Way back when, when I was a young, eager salmon angler, unfamiliar with the Trask, circa 1992, I went with a buddy who was better versed than I was. It was a very low-water year through early October, then during the week, it rained the perfect amount. This brought the river into prime shape (it actually cleared immediately after the rise) on a sunny, warn Saturday morning -- the perfect storm, river jam-packed with fish. We headed to the Trask, and scouted holes. We forgot to bring our own rock, so we kept heading upstream. Since there was nowhere to park anywhere on Trask River Road, we finally found a spot, and took a walk down the trail to at least see if any of the 287 people were hooking anything. It was a narrow spot in the river, and a shallow riffle. Both banks were elbow-to-elbow flossers. Then one flosser tangled up his 43 feet of floss with a flosser on the opposite bank. Mind you, we had just walked down the bank to take a look, and immediately saw this go down. Instead of the usual "sorry," then the "more guilty" party releasing his spool, these guys started having a tug-o-war across the river for the gear. Well, they were having a tug-o-war, until one of the parties became irate... and (bear in mind it's elbow-to-elbow) pulls his piece, and starts putting rounds in the bank next to the guy.
I can't tell you the final outcome, since we ran like scalded banshees up the bank, and head for the Wilson. I do know by the time we got up the bank, there was at least 20 other guns being brandished.
That stream attracts a rough crowd.
