Probably not as constant as Ink, but I generally spend a few days a year usually when the fishing is kind of slow putting in new brush and adding to the old ones that were productive. Last summer I didn't sink quite as many as I usually do because my fishing partner got us a SI depth finder. I spent that extra time riding and found other peoples brush instead......it was alot less work...lol. Around April I have some good spots in mind for some brush that I will probably add when the leaves get back on the trees. I think the green leaves draw the bait better, so thats why I am waiting until then. I got about 12-15 christmas trees drying out to sink now, but haven't had time to sink them. Last year Crappie Buster and myself collected about 30 christmas trees and spent a whole day sinking them. They have been very unproductive on Murray, so these will not go on Murray. That was the first time I have ever sunk christmas trees on Murray and it may be my last.
