Prefixes, portables, and added crap

[CASEDA at ECSUC.CTSTATEU.EDU]

Okay, if it is okay to sign KA1NCN while I am operating portable
in California, is it okay to sign i t if I am in Alaska?   
I don't think that there is anything in the rules about signing
prtable KL7.

But what really steams me is this....
there are always a couple of guys in the WPX contest who
sign something like KA1NCN/NZ1 from their home statinoon, to boot.
Any thoughts on this.
