You will not get 29- but here is an idea. Sell it or wait for the dear to go through and buy Trans Canada a good company that will now be even better and maybe with a new administration next year the Keystone deal with go through.
Sometimes shareowners don't want to wait for the difference especially if they have other and better uses for the money. And the deal could fall through and then again a higher offer can emerge. Looks to me like a good one to just sit tight. good luck
