MI Census Tract Boundaries

[Troy Wiora]

Do census tract boundaries change from year to year?  I have 1997 or 1998
boundary data and I just do not know.

Thanks All
Troy

MI Mid-point line between multiple points

[Troy Wiora]

I am looking for some way to create a line of midpoints between three points I
have.  I hand drew a line that looks like it is in-between the points but I
would like something a bit more exact, if there is a way.  Specifically, I am
drawing three shapes showing which roads are closest to which of  three fire
stations.  I can e-mail a jpeg of what I have already done if it would help
clarify anything.

Thanks
Troy
