My understanding was that only an idiot would use WIDE7-7 unless there
was a real need for it. It's been a while since I have seen it used, but
I do from time to time see WIDE1-1,WIDE2-2 and other combinations that
yield even several hops more than that. If there was some emergency that
required going more than the recommended number of hops, SSn-N would be
a good candidate as it could stay in BC or WA etc. as the case was. Even
something like WA3-3,OR3-3 could be used to get from "here" down to
California if need be (assuming there enough digis with support for
SSn-N down in that direction) but certainly not for everyday use!

You are right... WIDE4-4 could potentially make it from "here" (not too
much north of Seattle) to at least northern California. For normal use,
I would consider that an abusive path too. It certainly shouldn't be
used in normal day-to-day use. It would have to be some kind of an 
unusual event, such as trying to deal with some kind of disaster 
situation. I would never recommend use of WIDE7-7 unless there were very 
exceptional circumstances, and even then wouldn't expect it to be overly 
successful in reaching that far. Hopefully we see more use of WIDE7-7 by 
idiots than we see "proper" use of it during disasters - hi!
