I'll be there in October for a business trip, just wondered if
anyone in or near Evanston does outcall.

Sweetsusan is close by and she does both incall and outcall.

Susan is not located in that area anymore.  She will do outcalls.

There's a woman named Colette, who has an incall a little south  of the Loyola campus.  She has an ad on RS2000.  No website, but her number is 312 320-5317
