Nice baskets, and course is generally well kept.

The course is meant to be accessible for all skill levels, but general course design was pretty poorly done. Very few right to left shots, which would be most beginner-friendly shot shape. Several holes where the ceiling is too low to reliably throw under, making the best play to just throw over trees or tennis courts. A lot of maintenance of the low hanging branches would help, especially since you don't get ground play on the grass. Additionally, when they're able to install cement teepads, this will be a much better course.

The name of the course is annoying. The course is located at Hall Memorial Park, commonly referred to as Hall Park. No one refers to this park as Memorial Park and certainly no one calls it Memorial Field. Hall Memorial Park Disc Golf Course or Hall Park DGC makes much more sense.
The guy who runs the Facebook page for this course makes it hard to follow the course Facebook page. It's not normal to make posts under the page's account. If you want to share information, you should post from your personal account on the course page. Also not normal to comment on other pages using the course Facebook page. Just use your personal account to post, and add yourself as a moderator.
Other than all of the stuff above, it's a place to play when I don't want to make a trip to Vacaville.
