From Chicago, please.

Love this interesting guerrilla/transit media buy. As part of their sponsorship of parking at Copper Mountain ski resort, FirstBank has a "helibus" with 25-foot blades. Its messaging of “Heli-Skiing, now as affordable as Free Checking.” plays right into FirstBank’s efforts to get 18-34 year olds to open checking accounts with Colorado’s largest regional bank. Unfortunately it can’t fly, just taking skiers from the parking lot to the slopes.

I’d get on it just for the photo op.
