i am afraid of heights. one of the more memorable wire pulling jobs involved a man lift. not real high, but high enough to make me nervous. but the scissor lift was sooooo much better than moving & climbing a ladder. and felt safer than the ladder also. it was a huge place and the wire runs were longer than i had ever done before. they needed some mesh nodes at various places, and network access for their cash registers and some network phones and work stations.
