Just left a session with dave and his gunge filled dunk tank and just wanted to say what an amazing experience it was. I was pretty nervous beforehand but dave has this knack of putting you at ease. The gunge is incredible, it's so perfectly thick, just like the good old days of get your own back. I couldn't believe when dave said he still had room for sessions this week and next. I can't recommend it highly enough. Cup of tea and biscuit to finish to round off a great morning.
