I used to compete in 20km obstacle course races a few years back but there's no way I'm prepared to climb over fences or gates for work!it very rarely happens but it only takes 5 mins to get the ladders off and hop over a gate....i will only do this for higher paying longer frequency jobs though...i dont want to do half a job and then not clean the backs for another 6-8 weeks which will be 12 or 16 weeks without the back windows being cleaned...all because i couldnt be bothered to get my ladders off.....
