<p>Psh, not everyone goes to 4/20 just like not everyone participates in First Rain. Many people do avoid it and are deeply annoyed bus services to the west side of campus are limited (and guests are limited) during that time. Several of those who show up are ones who snuck onto campus and have zero affiliation with it. First Rain is usually just UCSC students (highly likely this is related to it being unpredictable when it will happen until the day it happens, though).</p>
<p>Besides, I don’t think Porter Meadow could even hold everyone. Everyone would be about 16,000 people (give or take) just counting the undergraduates.</p>
