Thanks sellickbhoy
found it!
OH has plans drawn up as we speak-looks spookily straightforward.
piglets arrive next week and will clear the ground then up it goes- or away it goes in the wind- one or the other!
we're going to use wood instead of plastic tubing- it should last alot longer and be more durable- will let you all know how it goes (or not)
...should make great piccy opportunity- anyone ever seen a flying ploytunnel before?
