depending on your location you might want to check out the Mountaineers or the Mazamas, or the outing clubs of local universities to see if they would let you go on trips. you can always find someone motivated to learn beyond the basics in such clubs and organize your trips. also, if you go to high school ask around to see if there is a teacher who might sponsor an outdoors club, then organize trips or bring in trainings yourself. check your local area for any climbing seminars around. any of this would allow you to meet other climbers face to face before committing to a climb with them. read, read read, and practice rope systems in your basement or yard so you will have an idea of what you are doing before you go out trad climbing. also, if you get your hands on a rack go to bouldering areas and put a harness on, place as much gear as you can at eye level, and jump on it with all your might to start understanding what will hold and what won't. good luck, be safe. trust your intuition as to who might be sketchy, and don't let desire to climb lead you into unsafe people situations.
