go out and purchase one or two of those oversized rubber containers they sell at places like wally world. Save the various bubble wrappings glassware tends to come in when purchased, if not saved no biggie, you can buy it by the roll at places that do packing, think "brown", also save those annoying styro thingamajiggies. Now line those containers with the sytros about 1/4 way or more depending on what your packing for a kit and place your various items in whatever bubble wrap is on hand. This setup is cheap, very easy to get moved if need bee, and blends in no matter what the occassion.
You got to go? No one would think anything of you for throwing a couple in the back of your ride, or sitting in your basement under a blanket or pile of newspapers. One containers can easily hold (4) 250 rounds (2) 500 rounds (1) 1000 erly (1) flat bottom (1) 1000 round bottom, a sep and 500 ml addition funnel, magnetic stirrer, 2 stands, etc, etc.... er... at least that what I hear

Ok so we wont get into the second container.
Plus the rubber insulates as well for those that don't have the soft touch. :-) As to the preferred location? One would assume anywhere that is not conspicuous. I'd be the person who against better judgment feels the need to tinker at 3 in the morning. Now this is not unusual since many know me to work graves anyways, however a different story if you are tearing away in your shed in the backyard in order to get at your toys now wouldn't it? Either way good luck.
