    The 92 bus not only serves the science park community but is also frequented by Henry Park and Nexus students. Most mornings there is no bus passing Henry Park until about 7am. Then several buses in a row appear. This bus is packed with kids trying to get to school/swim practice who are late. Is it possible to get a bus that passes this spot at 6:45 and space the buses out so they are 5-10 min apart from there? It seems that it is the time the bus is just starting so several leave at nearly the same time but the 92 isnt best serving the needs of those people who use that line. I’ve also noted that the buses are often bunched together more often in the last few months. So two will come back to back and not another for a 1/2 hour. It is very frustratiNg.
