MLS: Does the 'Rocky Mountain Cup' count....?

Its not a true derby. The only true derby in MLS is LA Galaxy vs. Chivas USA. Clubs are too spread out in America to have true derbies. MLS would like to put a 2nd club in the New York City area. That would create another derby. I think MLS should consider placing a 2nd club in Toronto in the future. Toronto seems to have a proven soccer fan base.
