There are a lot of valid pros and cons that had been discussed - Golden Mile, lots of controlled land, great grabs, stock support, but not yet located veins, disappointing releases ..
However, one thing that can't be ignored is the Richardons picking up stock on the open market. That says a lot more to me than the in-house rule "no insider stock to be sold". I don't see any way the Richardsons could fudge this - if they were selling KXl short or options short or some other way to hedge their "long" position, it would have to be declared in the insider reports, to be legal.
This is the "WTC 7" (if you can stand that allusion) of the KXL story - it can't be explained away.
Now, if we could just pin down a best guess on the next news release ... / cedartree
