Same reason the guys did, I suppose, it's ridiculously fun..ahem, I mean it's a learning fantastic opportunity.
Personally, I found my school team sophomore year (we didn't have much advertising then) through a marching band friend. Little did I know I'd spend the next three years growing more and more obsessed with the organization and end up spending upwards of 20 hours per week (30-40 during build) working on and managing that team! (Ok, so there are less-than ridiculously fun times now, welcome to life.) Then again, our albiet small team is more girls than guys (member schools are all co-ed).
