Unfortunately after only a few launches a new employee at the park decided that we couldn't launch rockets because of concerns about grass fires. This was a surprise to us because a) it wasn't even remotely dry, b) the other employees at the park had no concerns about grass fires, c) the Park HQ was ok with us doing it, and d), there was a large rain storm heading our way.

But since you can't really argue with park employees in this kind of situation was started packing our stuff up.
