when i was s student (22 years), i took a job in omaha that flew me out for three weeks at a time and i was making good money so i decided to finish my license there. i did a recurrency jump at my dz, took my logbook to weeping waters, and told them i wanted to jump. they looked at my logbook and put me through my ep's, and made sure i knew what i was doing and i did the next jump with them. i can't recall exactly since it was '06, but i think they even called my dz to check.
it was great except for one thing: the dz was huge! must've been hundreds of acres of flat land all around the damned landing area. i was very much used to locating the dz by using the river and hills, then looking for an open spot. that really sucks ass when it's all a huge open spot. i also did a couple of student jumps at raeford, but that was afterwards, so i knew what to expect. of course, when you learn how to skydive in a landing area the size of most d license landing areas, you're good almost anywhere you go. our landing area now is about 2700' x 500', with almost every obstacle you can name surrounding it; trees, hills, river, powerlines, railroad tracks, buildings.
strictly from my experiences years ago, i would not recommend going to another dz as a student until after you are cleared for self supervision. as others are saying, you may find cliques (clicks?) on each dz, in fact you will, but it isn't that bad (strictly from my personal experiences at a couple of other dz visits with a license). of course, it never hurts that i walk into a dz with a case of beer the first time. if you don't drink, bring a case of water or other beverage.
