This was taken before the encounter with the puffadder yesterday. Lourens River running through Radloff Park in Somerset West. I shudder now to think of the reeds I clambered through to get closer to the river bank. Anything could have been lurking there!
Thankfully, nothing was lurking to prevent this magnificent photo. In general snakes will go the other way given the opportunity to escape. So perhaps you encountered some and didn’t know it!
