Today marks the beginning of Nike Sportswear's Air Max Sunset Scavenger Hunt. If you live in San Francisco or New York, then you're in luck. 49ers quarterback Colin Kaepernick and Knicks forward Amar'e Stoudemire will be dropping off hints throughout the day today via Instagram and Twitter as to direct participants to the key locations.  Getting involved is simple. If you're in the San Fran area, simply follow Colin on Twitter as well as NikeSF. And if you're in NY, lock in to Amar'e, NikeNYC and 21Mercer for hints on each location, as those who have earned the necessary NikeFuel points can win a pair of exclusive Nike Air Max sneaks. If you don't already have a Nike+ FuelBand, you may be able to win one at the first location or of course purchase at NikeTown SF, 21 Mercer and NikeTown NY. Four different locations have been chosen, with each location holding one of the four styles from the Air Max Sunset collection. Happy hunting.
