How about Thuja 'Green Giant'. When we first heard about them, I thought it was all hype, but purchased some starting three years ago, and they have grown fast, and still look dense. They grow considerably better if watered and fertilized well. Polly

Do deer eat thuja??
I also need a privacy screen and was thinking of using some of the millions of pine tree seedlings around my house. I don't think they're fast growing, but deer don't eat them here and when you clip the top of the plant, it bushes out and grows thick but not too tall.

yes deer will eat them, the only thing i have thats evergreen and untouched by deer are spruce, austrian pine, and japanese black pine. i have junipers that have been nibled on but seem to survive them nibling. the pines you have are probably austrian pine or scotch pine which will be a good hedge, but not fast growing.
