So far I've had several failed attempts but yesterday I failed my mission in spectacular fashion!
The method to achieve the goal is part spinning class, part Clark Kent style speed changing, single dry fly set up to target a rising fish between 1-2pm when there's a hatch coming off. That translates to10 mins hoofing it across town on the bike, 5 mins to set up, 30 mins fishing, 5 to tackle down & another 10 to get back to the office.
To succeed you'll need a bike, a rod, chest waders, knowledge of the river & a good measure of luck. I would advise caution also, it pays to keep your wits about you as river courses through urban areas tend to be the more secluded places especially the more trouty ones and naturally these out of the way places are a magnet for a variety of miscreants. On a recent failed attempt a 18 stone man looking like a cross between a bad transgender & an escaped mental patient came lummoxing towards me down a cut off bit of river bank in a wig, ill fitting dress & hob nail boots & was only deterred by me picking up a brick & telling him to fuck off!
