I thought that having access to crane equipment in the lab was very helpful in learning materials covered in the course. I look forward to taking additional courses
here, and I will recommend this course to my co-workers.

(What I liked most about the seminar was...) Their suggestions. Many of the
suggestions they had would help but they must be implemented.
