And you thought your commute was long.

A group of public transportation advocates Wednesday started a two-day sojourn from Jamaica to Montauk using only public buses. The trip involves 18 different bus routes, and aims to raise awareness about the importance of making additional investment in transit.

"The purpose of this trip is to say, 'Yes, there are issues. But when it works, you can get almost anywhere," said Aaron Watkins-Lopez, of the Long Island Bus Riders Union, which organized the trip.

The group planned to get as far as Stony Brook Wednesday night, before resuming their ride Thursday morning.

The advocates also say Nassau and Suffolk need to do more to make their systems accessible to all riders, including ensuring all buses have working audio and visual announcements, and Braille signs at bus stops.

A spokesman for the Nassau Inter-County Express, or NICE Bus, said the agency believes it complies with all Americans with Disabilities Act requirements.
