I was about half way round my trail (which is also the Spit Bridge to Manly trail) when i almost stepped on a two foot long lizard! Turns out these Eastern Water Dragons are sluggish that time of the morning and just park in the sun patches and don't move out the way! I stepped over the first one and then almost immediately ran on in to another. The next 100 metres were like stepping between puddles, but they were lizard hazards! Must be mating season or something!
At least they're harmless, but it did make me start to keep an eye out on the trail, which could be helpful considering there's brown snakes around this time of year...
