If you have one of these then I only have to find out who owns the other 33 that were sold and we an get together for a party ; outside (in a phone booth!). The title sounds a bit like somebody recently released from spending some time behind bars but the book is about creating (or more accurately having the kids create) a bean bag golf course and the other half is about setting up a maths trail in your community or within the school grounds. If you can find a copy of this little gem (there is 34 of us who like it) then photocopy it as it is out of print.
