Yellow School Bus

I got on the freeway after dropping steven off this morning and I saw
two school buses...

I don't remember ever going on the freeway when I took the schoolbus
in elementary school......

We live far from my school too...is it because it's san
Francisco???...because they never used to take freeways???...or was it
just my school bus???...or maybe it's just that I never used to pay
attention....I wonder...
