[CAUT] jack repetition

[Chris Solliday]

Jon,
I liked your description of what is going on with jack motion. I too in
institutional settings often run into the same wall but we are always
negotiating for more money and sometimes it bears fruit. Fortunately I do
get to work in other settings where the edge is kept in place with
vigilance.
