I'm amazed by the cost of wood. Here a 2x4x8 is $3.09 or pressure treated is $4.85. Since we already have a gallon ($50) of Cedar Penofin we are debating going with Douglas Fir to save on cost. What are everyone's thoughts on this? Oh, this is for our walk in run. A good majority of the run will obviously be welded wire and hardware cloth. What did you guys use?
