Monday Night Rehearsals, or as they are more commonly called, "MNR", is when the California Aggie Marching Band-Uh, also called the Aggie Band, gets to practice all the kick ass songs they play. These rehearsals usually happen at the ARC, on Monday Nights, from 7 to 9pm. Show up to one if you want to join. Besides, the Aggie Band is way cooler than the Aggie Pack, since they travel to places. Like Texas. Or Washington. Or South Dakota.
