My outdoor is 150 x 300. I'm admittedly a tightwad, I have wood post & 5 ft high red brand horse fence for arena fencing. I'd love to have pvc but have better things to spend my money on. Lighting, I have dusk to dawn lights on telephone poles on each corner that the utility company installed for me and they charge a flat monthly rate for, saves quite a bit in the long run. Winter I don't use it but they still run, summer it's used A LOT, I'm often riding until well past midnight so it evens out. They aren't floodlight bright but more than enough to ride safely in the dark without creating stark shadows.
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
