Think that was Edgeley Park (Stockport) where they played until the 2012 season.
It was notorious for the sand covered muddy pitch edges, and it was because of this we had the Pizzagate episode.
Following one of our props nearly drowning in liquid mud a few weeks before at Vicarage Road, the PRL/RFU agreed with Wasps that if they came across such a pitch again they could refuse to play on safety grounds.
This happened at Stockport, and even though extra sand was added, the mud still remained so the match was called off, and the Wasps team got on the coach home where Pizzas, that were always ordered for the return coach, were dished out, much to the ire of Sale fans who never let us forget it
