bottlejunky. You said you have 3 kids. start them off by having them research the bottles on the web. the history of the area, the history of the bottles. Also have them check ebay for similar bottles. nothing like seeing a dollar value to get the kids excited. finally, go out and dig with them this summer. its better than sitting in front of the TV. take them to the library and get some bottle books out. kids love to get dirty, cleaning bottles on a hot day is a great way to cool off with the hose. also check for local bottle clubs and possible shows. you've stepped into now and there's no going back. you're only problem is you've hit the mother lode on the first try, its not always that easy but it is always fun.
