(We were waiting for the illuminations to light up. Thought they were pretty poor to be honest. The lights from Central Pier to the Pleasure Beach wouldn't come on, and a very old tram broke down blocking Fleetwood bound trams just before Central Pier. Then the lights from Central pier to the North pier went off again. This was 8.20pm.The traffic was sparse.Never seen it like that before.)
One 'tectorist was on the shoreline and the other was in the small cuts in the sand.
I would have approached and introduced myself, but my better half was having none of that.

I've never done beach tecting, but they seemed to know what they were doing.
