Pros:
Location---this course begins to fill a desperate need for courses in the MetroWest
Tees/holes are not difficult to find (if you know roughly where to go---a sign on the top of each basket tells you where to look for the next tee)
Family friendly---my wife, 2 yo son, and 5 yo daughter completed the course with me (the most I was able to do with them previously was 5 holes at Amesbury)
Cons:
A map is helpful the first time you play---print out the map in the Links/Files section here; if your printer is b/w, mark the hole numbers and arrows with a pen
Baskets are DGA M-14 (or very similar); I have an M-14 at home for putting practice; these are lower quality than most players are used to; I had one putt hit the center pole and bounce out---this would not have happened on a higher quality basket
Fairways cross pedestrian paths (#1, #7, #9) and a sports field (#6, #3)
Minimal challenge
Other Thoughts:
Update 12/26/15: baskets have gotten an upgrade (heavy double chain). Except for #6, there's a permanent post with number at each tee.
Maybe they weren't when Hector Chain played, but the few baskets I inspected were secured via metal stakes---not ideal, but reasonable considering the course.
We were here Sunday morning on Labor Day weekend; we saw only a few people---we had no trouble playing the course. I can see this course *not* being fully playable most days when school is in session.
We had trouble parking around hole #1; instead, we parked at the lot near hole #4 (first right after you enter Olin) and started the course from there.
If this is your closest course *and* you can come when school is not in session, I would recommend this for someone who is looking for a short outing and/or drive/mid-range target practice.
I thought holes #1, #4, #7, and #8 were the highlights of the course. #7 and #8 have narrow fairways and require an accurate (albeit short) drive for birdie. #1 is downhill and has interesting terrain and scattered obstacles. #4 runs along the edge of a wooded area and has a dogleg left---an overhanging tree will trip-up a poorly-aimed drive.
It's disappointing that the course doesn't make use of more of the nearby woods (to the east of where the current course is).
