Don't worry about it being the third application in five years. It would be unusual for the same person to be reviewing resume five years down the pike. (Application are rarely retain more than one year if that!) Tell them it has always been your dream job and why (don't include the commuting distance.)

I think second place for a national design contest would be great to mention.

Maybe you can think of something that expresses WHY this is your dream job to illustrate....
