N2O Resconance

I hope it's fine for me to ask a quiz question. How exactly would you draw the lewis structure for N2O with resonance strucutres? I made oxygen the central atom, but I only realized that was a mistake after I turned in the quiz. So how should I approach this problem correctly?

Nitrogen ends up being the central atom because it is the least electronegative/has the lowest ionization energy. From there you simply juggle single/triple bonds, comparing the formal charges and ensuring that the compound obeys the octet rule. The structures with the most stable formal charges are what you use for resonance.
