During the summer of 1924, Strong met with Wright to discuss possible schemes for its development, and by September of that year had fixed upon an ambitious program. As he explained to Wright, he wanted to erect "a structure on the summit of Sugar Loaf Mountain" that would "serve as an objective for short motor trips," primarily from Washington and Baltimore, both nearby.
The Strong project celebrated mobility in a way no other design had, for while there was ample precedent for spiral structures, none had been conceived in just this way, nor been so fully integrated with its setting. Neither had roadways been so dramatically recognized. Strong rejected the design, feeling it inappropriate, and built a more conventional park instead. Wright, apparently captivated by the spiral, continued to develop its potential in several later projects, of which the Guggenheim Museum (1942-59) is the best known.
