The twenty quid challenge

Right new drinking challenge ( as if breaching the smoking ban wasn't enough) instead of spending mucho dollars on drink, is it possible to go out for the afternoon and get several drinks and keep your bus fare for up the road?

Right so find a trusty companion for these proceedings, and off you go with said £20.

Start at thee Ark (friendly pub for smokers as they have a beer garden :-) ). Start off in theory cheaply. £1.80 a pint cant go far wrong. Then realise that bunker does £1.20 for drinks all day. Hoof it up to bunker as pub mathmatic dictates that for every 2 drinks at the Ark you caanbuy 3 at Bunker.
