My son and daughter-in-law are staying tonight, so at about 7:00 pm I went to open the gates to our drive. I took a torch with me and the first thing I saw outside was a rather large toad.
Just by coincidence, as I opened the gates my son arrived, and drove his car straight in. I went to close the gates as he got out of the car and as he did, something shot past him out of the gate and across the road. I shone my torch on whatever it was, and saw a huge monitor lizard, must have been about 3 foot long disappear into the long grass. I didn't have a camera and it was too dark anyway but this is what it was:
I'm pretty sure he/she wasn't dangerous but it moved pretty fast and so startled us a bit. I'll certainly be more careful when in the garden at night from now on.
