My Vertical Frame is Complete

I built my first vertical frame today.  It was really easy and cost me 15 bucks.  For some reason my poles are not 5' tall but about an inch shorter. Guess I cut it wrong.

I've decided to plant my cantaloupe on the west side of my 4x4 and will plant my tomatoes on the north side.  Thinking about getting some tomato cages instead on another vertical frame.  SFG says that you plant melons one every two square feet.  I'm going to do that, but I am also going to plant some pole beans in the other squares to grow up the frame.  Hope it doesn't screw with either plant.  We shall see.
