I am looking to set up two poles in the back yard... I have two options with little cash difference...

Option One... is 2 3/8 oil field pipe, ten foot long buried 2.5-3 feet 15 feet apart... 1.5-2 bags of concrete in each hole...

Option two... 3 2x4x10 two screwed and glued together with the four inch side together and then the third one screwed and glued perpendicular to those two on the end... 2.5-3 foot deep, 15 feet apart, 1.5-2 bags of concrete per hole...

The wood is about $10 cheaper when its all said and done... But either way I'm sure it will out last any hammock needs for the next few years...

Which would you chose and why???
