I may be a ble to help...but probably not until the 3rd week of March (Spring Break). Between teaching (Jr. High) and working part time jobs (OSU events, two gardening jobs and once a month estate sales) I don't have much time other than an hour or two in the evening with family.
If I do get a break before then, I'll go to the OSU library to check on maps for you.
