Hmmm... we are lacking in leisure facilities - nobody will argue with that (unless they are keen golfers in which case they'll be as happy as larry!) - so with the need to travel elsewhere... lets see if we can produce a list of "things to do" and where to go for them...
I'll start off, we make use of the following facilities/areas:
Swimming - Rainbow Lesiure Centre, Coulby. We tend to go early Sunday afternoons, 1pm ish - often get the pool to ourselves which is nice.
Park - Ropner Park, Stockton is very nice. Large childrens play area, cafe and duck pond. Strangely more enjoyable in the winter for some reason (less people I guess). Great for conkers

. Can be reached by bike - but going under the A66 can be tricky cometimes.
Also
Preson Park is cool too - loads of space to kick a ball about, walk down by the river or make use of the cafe and play areas. Also easily reachable by push-bike (that's an amazing human powered 2 wheeled mode of transport for you petrol heads!).
Walking - River Tees - It's actually quite nice to have a walk down by the river near to Roundhill - kills a few hours and you can easily foget that IB is a few hundred metres away.
Walking again... there's a walk we call "the hilton" walk... park near to "The Falcon" pub (is that right?) - and walk along the bridleway opposite the pub alongside the new houeses. Follow it down into the woods alongside the river leven - you eventaully end up walking along the valley under the A19 flyover between the A174 and Crathorn junctions. It's a great walk, but can be a bit muddy.
I think that'll do for now... anyone want to add more?
