Yesterday Mitch Albom had a person on his radio show from DC thats works for some agency regarding fireworks and things like that. She said in about a year from now things should expand on what you can buy. The current laws are from 1966 in Michigan and that there is an attempt to gain revenue by changing the regulations.
Another interesting thing she said is that in Ohio you can buy the good stuff, but you cant use it in the state. In fact it has to be out of the state within 72 hours of purchase.
