i was trying to find a map that Wok posted a little while back and it had the exact location marked on it but then had a dinner break so davidb bet me too it :lol:
I just took a butterfly net (about 10-15cm diameter sorta thing) and it caught them fine. Every scoop you get 1 part Molly, 99 parts Mud so its a mission to seperate them lol
Take spare clothes, buckets, Nets, and Bags... oh and old shoes and Socks to wear in the mud.... trust me, you need them!
