I have been reading this for sometime and we live in a city with several new playgrounds and frankly most are not very usable!
The equipment is one thing, there just seems to be a few things that are missing (may or may not apply in your case OP) - #1 bathrooms! lack there of- older people and small children go- and local stores (one new playground is not even near anything!!) don't take kindly to asking and when none are around that shortens or doesn't even make us want to go there
#2 seating - if you are elderly and are watching small children - good luck having a seat (in my area) - we have one and they only have ONE bench
#3 I would love some SHADE added to a playground - for the young parent with the baby and the older grandparents, with seats under it
these tend to be all after thoughts (as when the complaints come in)
doesn't matter how great the stuff is for the kids, if the person going along is not happy with the accommodations-IMO
