Thanks Guys, great video and some good information.
In following with your theory of safety while out back, just a suggestion, but Wal please put a helmet on when riding T-Rex ! mate one slip and fall on the side with all the rocks and it could be very nasty, especially for Liz dealing with an injured Wal !! You may be the worlds best rider, but even they fall off from time to time. Just a thought mate.
Even a bike helmet is better than nothing.
