In reply to Geezuz:
you're better off with manc wall, its closer for a start compared to rochdale at least 45 mins off train etc from city centre
there's more of crowd so you may have chance of buddying up for a belayer if you advertise for a partner before you go on here
there is also salford uni wall, but its small and not as atmospheric as manc.
broughton, unfortunately freezing until you're fully warmed up, but its a classic concrete wall with the 'new' boulder bloc
when are you down so people may want to parnter up for the night know in advance?
