She then proceeded to take frontage roads and side streets in a course roughly (and I use that term rather loosely) parallel to the freeway.
At one point when we were running alongside the freeway, we spotted the 817 ahead of ours, bogged down in traffic. Since we were moving faster than the freeway traffic at this point, we readily passed the other 817.
At this point several passengers congratulated the driver on her traffic-avoiding savvy, as did I, when I exited the bus.
We did eventually get back on the freeway. But we still got to UVU and BYU before the bus before us did.
