The biggest issue with not having a car in Abbotsford is not having a car in Abbotsford. Essentially, there are three options to try getting around efficiently without one. You could take a cab, which while convenient can be very pricey.
Second, you could find someone with a car and impel them to drive you (without committing grand theft auto). Although this option is free, it can prove troublesome and time consuming. For one, you must get to know the target on a personal level without making your intention known. (You wouldn’t want to raise suspicion would you?) And even if that is achieved, the person might actually have plans (and a life) of their own that can interfere with them driving you around.
Two down, one to go: the bus. It’s for free with your U-Pass, that’s a pro. It runs around the whole city, also a pro. It’s always late, con. Sometimes it doesn’t come at all, con. Finally, even when it does come, you risk not being let on because it’s full and the driver doesn’t give a damn about your schedule.
In conclusion, if you’re close enough to what you need, I suggest you to adopt the most reliable mode of transportation: Walking.
