I suspect you'll get "contact" as not being time dependent and "ascent" as meaning at all times while climbing (i.e. all pyramid contact for a climb must be in sequential order). That said, I'm looking forward to the return of the endearingly ambiguous Reasonably Astute Observer.
Actually, I believe the RAO has already returned briefly, but nowhere sufficiently hang-off-the-bridge-rail ambiguous.
Don, I think my kids are using "clumb" from now on.
