The Delorme Atlas has good maps with very nice detail. Some options:
Planned bug out destination: make color copies of applicable pages and then laminate the printouts.
Planned bug out destination: cut out applicable pages for getting to your destination. Laminate or plastic bag.
No destination: pack the whole atlas and then once you decide a direction of travel cut out what you need (or what you know you won’t need).
For northeast Indiana there used to be Uncle Larry’s Lake Map. Not as good but detailed country roads and lakes. Might try Reigel’s in downtown Fort Wayne although I think they are closing out their map section.
If you're looking for really detailed maps check out USGS topo maps. Available in different scales also and you can get them for any area you want. Best part is they're free to download so only cost is printing. Print on heavy weight paper, laminate, and you're set.
If you have AAA, they give paper state maps away to members for free.
