I live in Luton Sean and had a ticket two years ago,the spot I fed was the bird feeding platform where you aren't allowed to fish,but the fish were cruising all over,it was just a convenient spot to vie them,standing over three feet of water,I fed 8mm carp pellet bought from G&M growers,seemed to enjoy them,seemed to be cruising along in water around four feet,I went away for some chips and a drink(it was scorching),came back about two hours later and a common around 12lb and a bream around 6(had a mark near its tail) that had been there earlier were still there,they must have ate everything i'd put in,maybe half a pint,soon got their heads down when I put a few more in,you want to get there early for the tench as they soon melted away as the sun got higher,I got there at 9.30am,so fishing till 10am looks the best option.
