Interesting "ladder" you had there Brad. Now, there's an idea for a DIY project - a pedaladder.
Slightly different to what I had in mind - a ladder that you could pedal sideways to avoid climbing up and down to reposition it. In a way, that is what you have done but it makes working up the ladder somewhat difficult as it has to keep moving. Everything is almost always out of reach.Did that too!
Climb while you ride bike ladder!
Look ma, no brakes or helmet!!
