We have four (4) steel framed bikes here on the coast and have no problems with rust. As suggested above, Frame Saver the interior of the tubes every few years and wax the exterior every season and you should be fine. If you think you've gotten salt spray on the bike then rinse with fresh water and dry before putting away. Touch-up the paint periodically. Rust is not a problem given some simple and easy maintenance. Same that I would do regradless of where I lived. Have fun!!
