+1 for The Hub – great shop! Barney and the rest of the crew are star people.
Reasonably easy to get to Queen Elizabeth Country Park near Petersfield – not Cwm Carn but quite fun.
The South Western was my local and was pretty good, The Crown in Highfield was good, Cowherds was OK, The Wellington and the Waterloo in Freemantle were OK and the Richmond in Portswood was good.
Calshot climbing wall was pretty good – don't bother with the one in St Mary's as it was never open that much in my experience. In fact don't bother with St Mary's at all.
Lordswood was fun for a quick blast, but get up to Watership Down and the North Hants Ridgeway for a real blast, and get to Cheesefoot Head for some more good riding.
Look here for some ready-made cycling routes.
Go to Bitter Virtue in Portswood for some very good beers.
And steer clear of Southampton if you possibly can – the roads are dreadful and it has an even higher proportion of small-minded idiots than the rest of this country.
Struggling to believe that CFH lived in Viole(n)t Road and not in one of the Collins houses in Highfield and always had Hora pegged as living up north somewhere!
