I read with interest the Weekend Escape about the spa at Glen Ivy Hot Springs ("Club Mud," Jan. 15). I am intrigued enough to take my wife there. I am writing to correct an incorrect term: Glen Eden Sun Club is not a nudist colony ; it is a nudist park . Nudist facilities in the last few years have changed their marketing strategies, thus the change in terminology. A visit to a nudist park can be thought of in the same way as a visit to a water park, a wilderness park or a theme park. Besides, colonies are for imperialist cultures or social insects, neither of which appellation fits nudists.
