@divisionbyzero we used to do this when I was in HS for marching band practice. 6AM-11AM, before the heat, last 2 weeks before school started (after Labor Day).
@kismatt Marching band here as well. We did 8-12 then came back to do 5-8 in the last 2 weeks before school started. 1984-87.
@divisionbyzero It may have been longer than 2 weeks - I felt like the first 3-4 days were spent teaching the frosh which foot was the left and which the right. lol
@divisionbyzero Also, I think the drum line did the whole month, plus afternoon. I was brass.
