Hi there.
Its a rather odd fact but there does not seem to be any organised group in Sussex. Everyother county, from Norfolk, south and around the coast and over to South Wales has 1 ( with the possible exception of Avon).
But as Alex mentioned above there are regular meets in Portsmouth which normally ( well thru the winter) 2 hours in a gym, so no problems with the weather.
There is another ray of hope for you. I know of 1 other Bognor bocker and he is a keen regular and pretty good one at that. Works at Butlins. Doesnt use this forum but does use the JJ forum pretty regular. Goes by the screen name of 'Gibbo', not to be confused with 'Gibbo2' his younger bro , who lives in Havant.
Not too sure when the next gym meet will be as Christmas is comming in the way of things . Id hope there will be 1 on the sat or sunday b4 christmas and on the w/e str8 after new year ( if the place is open )
