You take hold of both keys, as you intend to explore both options. As far as the map goes, that could all be one big ruse. You might never know if you need both at once, and you don't intend to find out if you made a mistake later. You simply can't afford that. You find a way to fit the keys into your clothing, and take a direct route to the key card location. The city opens up going this way, and the streets you are traveling on leads you into a highway. This highway cuts the city on half, allowing for an easy trip to the gate. You decide for now to keep pursuing your goal, and head in the other direction. Coming across a rare and welcoming sight, a highway sign holds the numbers of the card on it, with the words "Fire Station" written below. You see the building it mentions, and head off the road towards it. You step into the parking lot of the station, filled with scooter bikes. You continue onward, approaching the one ridiculously large garage door. A black door sits next to the big door, providing a slot to insert the card in. You have the card at the ready, but consider the option of investigating the bikes first
How do you proceed?
