Im not the best person to rack, but I do have a little experience and here's what I always try to do when I rack: 1. If its the middle of the summer and your area is hot, don't wear baggy jeans and hoodies to drop supplies in. Its too suspicious and there are many more methods out there 2. You can stuff small items in your butt crack. Markers work perfectly with this, just stuff them vertically in your crack and try not to walk weirdly. Those are mine for now, what are yours?
