It even has its own Wikipedia page. en.m.wikipedia.org/wiki/Rol…. The bouldah itself sits perched on granite blocks in the middle of Main Street. There’s some landscaping and shrubs to contend with. There’s also lots of traffic. The climbing seems decent besides some calcified footholds. There are no ticks or chalking of holds.
