D.S.
I know you asked this a while back but while browsing I saw it & thought I would let you know that Haltom City just opened a new one. Here is a link to the city's webpage about it: http://www.haltomcitytx.org/HC_Parks_Rec/Pks_Broadway.html
Have fun! Oh, side note: the play pools in Arlington are a ton of fun. My 3 year old loves them!
