spring party weekend

<p>can someone explain about this, whether its really as good as people ppl claim to be, and when it is?</p>

<p>Biggest party weekend of the year. Usually a Wed to Sun event. The weather saw extremes. Two of my four years were beautiful sunny days 70F+, one cold rainy, muddy mess, one snowstorm on the Fri. It usually is the third or fourth weekend of April.</p>
