Can I start watching One Tree Hill with Season 7?

I’ve got the season 7 of One Tree Hill DVD from my friend and I want to know can I start watching the series from here? Or should I watch the seasons 1-6 before?
A1: If I were you, I should start from the season 1. I think this is a great show for watching! If miss the beginning of the show, you will miss a lot of things. It is so good, and you will get so much more meaning behind everything and you won't feel so lost. Enjoy your time!
