50!? You get different Scouse in the North and South of Liverpool. Then Lancashire on the outskirts which ranges from full wool to scouse, not including the weird mix in Runcorn. Posh Scouse in Cheshire, scally/want-a-be Scouse in Birkenhead, the other accent cunts have in Cheshire/the Wirral were they've purposely tried to dilute the Scouse. Then North Welsh, plus the hybrid the locals actually speak when people aren't around in North Wales. Think that's less than 20 miles. Tbf I'd even go as far as district to district.
