SO NOW WHAT? You've got the kite up there, it's given you some chills and spills and thrills, and you've grown accustomed to the tug and tension of the string.

Chances are you'll soon have a bad case of Is That All There Is. Kite-flying is a contemplative sport, and for people of a certain urban temperament, it can be, quite frankly, b-o-r-i-n-g.

So once your kite is high enough to amuse itself, consider one or more of these alternatives till it's time for re-entry:

1. Read: You won't get through "War and Peace" (save that for the beach), but you can blow through a breezy novel or a stack of magazines.

2. Before liftoff, make a tape of uplifting music for your Walkman. Stravinsky's "The Rites of Spring" will do nicely. Or "Also Sprach Zarathustra." Or even "Windy" by The Association.

3. Attach your hpes to the kite. Lie back and let your daydreams soar.

4. Write about your heightened awareness in your journal. (Or start one).

5. Write letters to friends -- if nothing else, you'll have a much more interesting opening sentence than "How are you? Sorry I haven't written in so long, but I've been so busy . . ."

6. Bring along a light picnic lunch. Share it with a fellow kite pilot, who will probably be appreciative.

7. Do situps or some other form of stationary exertion. Sure, you'll look silly, but it's good for you in the long run. And besides, how do you think you looked running around with a kite?

8. Make a kazoo with a fat blade of grass held between your two thumbs. This is sure to amuse, then annoy, everyone around you.

9. People-watch: Count joggers, lovers, tourists, other kite- flying crazies.

10. Try a time-honored tradition: Hand the string to the first kid who passes by.
