My husband is going for a quick visit to Houston and will check out all the areas you've suggested. Although I like the look of what I've seen of Montrose on the www we've decided not to persue that option as I think some of the other areas look better for young children. I've been looking at schools for all the other areas you've suggested. It seems that, if you're prepared to pay for private schools, then there's plenty of choice in all those areas. I think we're going to be spoiled for choice. It might all come down to budget - which we still don't know yet!
