JeffS, yes you are correct I have a short TTA commute. There is a TTA stop 1/4 mile from my house and a TTA stop 1/4 mile from my office. TTA route 310 goes directly between these 2 stops (Cary Parkway, High House, Davis Dr).
I moved to Cary from Garner last year and bought a house near the Cary Parkway. I really got lucky. I did not plan to buy a house near a TTA stop but I could not have planned it any better if I had tried. I don't think TTA is convenient for most people around here.
The TTA web site says all of their buses except the airport shuttles now have bike racks. The racks I have seen only hold 2 bikes.
