Hello and welcome!
Feel free to
introduce yourself here.Suggestions? Well first, read up around here, there's lots of info. Second, don't skimp on your first pick set, or get good at making your own. Thirdly, to practice, it's not recommended that you pick locks that are in use, because they can get screwed up. There are locks made specifically made for practicing available on the internet. "Habitat for humanity Restore" locations usually have cheap hardware, and scrap yards usually have locks lying around everywhere. At the scrap yards where you can poke around they usually have a lot of nice stuff. It's amazing what people throw away sometimes.
