Not sure where to place this question since it covers a broad range of groups and I don't know who is responsible for fixing it;
I noticed that Captain John Mullan Highway (Interstate 90) through Coeur d'Alene, Idaho and Northern Idaho Panhandle is misspelled as "Mullen". I attached a quick screen shot of the "Streets" layer from one of my AGOL maps - all the layers that name streets/highways have it misspelled.
