What parts of the state are you headed to? What cities?
As for pharmacies, Rite Aid is probably the largest chain here. CVS and Walgreens are both well represented too.
If you are in the Detroit area, and into industrial stuff, the Henry Ford museum, Greenfield Village, and Rouge Factory tour are very neat. I went to Wayne State and bought the year pass, as I was always in the area, and I still did not see all that is in there. »www.hfmgv.org/
I'd also recommend the Detroit Institute of Arts, and see the Diego Rivera Murals, Detroit Industry, they are iconic for Detroit. But the DIA is closed until November... »www.dia.org/the_collection/overv ··· id=58537
Post back with what cities you are headed to, and I will probably have other suggestions.--
The sooner we get behind schedule, the more time we have to catch up.
