Even when changing light bulbs or whatever .. easier to remove building or accessory and do bench work.
One of the most tediuos or difficult things for me to do with my 68 year old vision and hand dexterity is to re-connect wires to the wire clips under an accessory or building reaching 3 or 4 feet across my layout without knocking something over or worse yet, breaking something
Thanks Rob ... as they say sometimes you can't see the forest for the trees
