Yes, those conditions are; Summer, Autumn and Winter when the carp disappear into the Blue Yonder, the Sailing Club that controls half the pit, the waiting list for the syndicate that controls another 1/8th of the bankside and the 300k of boiliies I'd need to get them on to taking hookbaits since I appear to be the only person fishing "campaign-style" in this section. (Shrugs shoulders in resignation smilie)
The small number of very good carpers who fish here (Don't count me in) generally catch 1, maybe 2 between them in the 3 month Spring Season when the fish turn up in the bay prior to spawning. 100's of hours total blanking is the norm. However, you really don't know what will turn up.
And that's what keeps us coming back.
No boats or bait-boats, Tom.
