 I am taking care of an agency legacy system with a wonderful team that's over 100 years old. It needs a lot of maintenance and it needs a lot of care. And sometimes we have to re-engineer things. We have to look at things differently. In fact, we just pulled our trolleys that were built in the 40s back on track. And those parts are no longer manufactured. So our team had to pretty much think like I did with that erector set. Figure out how do we hold it together.
