We have another bus route to add to our repertoire. :-)
Although we haven’t yet ridden the bus through most of San Pedro, we take it *all* the time into San José! We catch it across the main street from the Outlet Mall (this isn’t full of outlet stores, it’s just the name of the mall). It is c185, and goes straight down Avenida Central to the terminus near the East end of the pedestrian boulevard.
The return takes you South one block, then East, following the old railroad tracks. This road curves back up to become Avenida Central again, where the route goes past the San Pedro Mall, the circunvalación, the Outlet Mall, and into San Pedro.
