Big Ben Wants To Visit Every County (Not Country)

To visit every county in England, Scotland and Wales (as quickly as possible) returning finally to Sleaford, LINCOLNSHIRE (home).

This TB is a Westminster Tower (aka Big Ben, although this actually refers to the bell at the top of the tower). Please move on ASAP, preferably to a new county.
