winter is lucky ... he was into the 'b' warrants at just the right time .... I think the lucky dog owns a truck load of shares in this company .... good for him .... 

you don't have a profit until you sell though .... but don't be in a hurry winter with PTA ...too many long range good things happening here ....

I don't own the 'b' ..but rather the raw stock mostly  and the reg warrants ( exp Oct ?, 2014 )....not in any hurry to sell either....... hope the 3rd quarter news next week is a company maker .
