I put my bike on the 7:36 AM #3 bus at the 38th and Medical Parkway stop. There were 27 passengers, counting me. (I took the #3 instead of the express because of my experience last time and because I was a bit early, so I could choose to sit outside for 10 more minutes or just get on the bus).
When passing underneath US 183 on Burnet Rd., there were 10 passengers, counting me.
When passing underneath US 183 on Braker Lane, there were 5 passengers, counting me.
And you wonder why you suburbanites only see empty (or in this case, near-empty) buses?
