  The classic question of whether one should walk or run in the rain to remain
the least wet has inspired a myriad of solutions ranging from physically
performing test runs in raining conditions to mathematically modeling human
movement through rain. This manuscript approaches the classical problem by
simulating movement through rainfall using MATLAB. Our simulation was
generalizable to include snowfall as well. An increase in walking speed
resulted in a corresponding decrease in raindrop and snowflake collisions. When
raindrops or snowflakes were given a horizontal movement vector due to wind, a
local minimum in collisions was achieved when moving in parallel with the same
horizontal speed as the raindrop; no local minimum was detected with
antiparallel movement. In general, our simulation revealed that the faster one
moves, the drier one remains.
