Around the Dayton/Xenia/Fairborn/Springfield Ohio area are some good hotspots.There is a Buffalo Wild Wings in Huber Hts.off I-70 and SR 202 that has access,and another one in Beavercreek off I-675 and N.Fairfield Rd.There is also a Panera Bread near downtown Dayton that has access.I am hoping the Panera in Beavercreek(same exit) will have it soon as well.Also,most Flying J truckstops have access too.They charge I believe $4.95 a day for access,but they have it.It is run by TON services(a company they are in with) and is pretty good from what I hear.There are other spots as well,but I don't remember them offhand.You can go to
www.jiwire.com or
www.wififreeaccess.com and look them up.The ones I have placed here are ok spots as far as signal,etc.Have a great day and happy hunting.
