"This year's version is 35' x 70' (next year will be 40' x 80') and has been a lot of work due to the warm weather we've been having. 

I have built full size boards, painted them and put up a backstop to keep the pucks and tennis balls in.  I have eight flood lights which provide more than ample lighting, I haven't used a liner in the five years I've been making them, but am considering it next year.  We have a walkout basement that turns into the neighborhood warming house.

We usually get 10-12 kids per night playing hockey till about 9:00 pm.
Last year, we had one day that we didn't have anybody skating on it (windchill was bitter!).  The kids love it and so do the parents.  I have noticed that I have more dads & moms playing this year.

I flood nearly everynight and try to get as thick a base as I can.  The thickest area right now is about 8-9 inches.  This allows it to weather several days of warm weather and still be able to play."

Thanks for the picture Dwight.
