Ok.
What about end of terriced and semis that have a garage on side of house.
Do you climb over the garage and drag the hose with you, or go through the house, either with the hose or a backpack?
The reason I ask is that WFP method is supposed to rid you of having to use ladders, so having to climb garages sort of defeats the aim a bit, or is it just something you have to account for?
