I have a MN friend (not sure if she's still on here) whose elder dd has just finished 6th Year and is off to Uni and whose younger dd is (I think) going into S4 and she's been very happy with Strathaven Academy.
Strathaven Academy is an excellent school and Strathaven is a great place to live.
There's not an awful lot to do for teenagers but there is loads for young kids. Lots of SAHMs and a lot of daytime activities.
Pros - lived there 13 years and was never snowed in. (I worked in Glasgow) - very reliable commuter bus into Glasgow but you are stuck with times there and back. - strong sense of community. - wonderful public park - good swimming pool and sports centre - some good events held - annual Gala Day, Balloon Festival, Agri Show.
Cons - A lot of new building means it's grown significantly. That might impact on schools - public transport is pretty useless. Need own car.
