I cannot believe I didn't think about this sooner...

I am taking my students on a field trip tomorrow to see a play at a local university and I completely forgot that I'll have to somehow pump twice while we're there. I am the only regular teacher going, but luckily there is a special ed teacher and assistant coming, too so hopefully they can handle the kids while I sneak away to pump. I'm not even thinking about where I'll pump.... I won't even have my car! Oh jeez, what a mess.

Have you ever had to deal with anything like this?
