Richard displayed his immense knowledge of the area as he guided us through the streets and subways. His voice was articulate and interesting and his manner pleasant and courteous. He tailored the tour to suit our expressed needs and adjusted it with no apparent difficulty as we neared completion. Richard came across as being interested HIMSELF and this made it so for the whole group. The only suggestion I have is to schedule more drink breaks including the option of a beer - the walking is thirsty work !
