On forts.

If you build them in very close by (neighbouring provinces). They will take recources from eachother (still) based on the admin value. Thus admin 50 will take 45 percent of the recources of a adjacent admin 5 fort. This can be bad if there are some unique units in that 5 admin fort, or if it is a strategically good place to recruit.
In a another scenario you have an admin 50 fortress that has a neighbouring fortress (1 tile away) with admin 50. They will share at least one province. This province - as all provinces - can only give 100% resources, and it will thus be drained, splitting (admin 50) its resources up between the two fortresses.
Do you want it to be drained of resources? Well, it is up to you.

Actually no, at least they're not supposed to. Forts draw resources from provinces around them, but not from provinces with other forts. Of course this still means placing them closely isn't too good. Ideally, each province has enough forts neighbouring it so all resources are used up, i.e. two 30 admin and one 40 admin fort. Practically, forts are useful for provinces with a lot of mountain/forest neighbours, at least if you need it to buy high resource units.
