  We are conducting a large program with the NRAO Very Long Baseline Array
(VLBA) to measure trigonometric parallaxes of massive star-forming regions
across the Milky Way. Here we report measurement of the parallax and proper
motion of methanol masers in S 252 and G232.6+1.0. The parallax of S 252 is
0.476 +/- 0.006 mas (2.10 [+0.027/-0.026] kpc), placing it in the Perseus
spiral arm. The parallax of G232.6+1.0 is 0.596 +/- 0.035 mas (1.68
[+0.11/-0.09] kpc), placing it between the Carina-Sagittarius and Perseus arms,
possibly in a Local (Orion) spur of the Carina-Sagittarius arm. For both
sources, kinematic distances are significantly greater than their parallax
distances. Our parallaxes and proper motions yield full space motions accurate
to about 1 km/s. Both sources orbit the Galaxy about 13 km/s slower than
circular rotation.
