I strongly urge you to get some finds before worrying about putting out caches. Too often folks get so fired up about putting out a cache that they don't realize that it takes some effort to place one.
Find some. Try to keep in mind the elements of the ones you truly enjoyed finding and let that guide you in placing your caches.
Give yourself time to settle into the game. Go find some more caches ... and not just caches in parks. You might amaze yourself with how many places are still un-cached.
