I have a few things that I have come up with but don't know how to go about getting them started. There have also bee things in the past I have either thought of or used that are now huge sellers. Take the block for example. Ever since I was 12 I have been taking scrap cardboard and stacking it in layers to compress and shotting at that. I know alot of hunters who have done this over the years. It took one guy to do it with foam and now he's rich. Oh well, maybe someday.
