Replying to Creative control over park

This year our park crew is building as many new boxes as we can as we just got a good deal on the P-tex stuff.

we have 120 square feet of box material.

The one thing we have decided on right now is a nice battle ship box (up/flat/down).

what else should we do?

we have a medium sized park with about 12 rails and no boxes so this year is a year to build some?
