Local regional anything rally near Marietta Ohio

Little bit of trouble finding events. Anything off road rally.

Your best bet is to use a multitude of sources:

Go to the www.ovr-scca.org site and contact the OVR rallycross folks to see what contacts they have.
Contact the folks at Central Ohio Rally Club - www.corc-rally.org
Go to the sites where most event registration happens and search for events: www.myautoevents.com and www.motorsportreg.com
Check other SCCA region sites. Not sure where you are but
Go to the main SCCA site and look for contacts there. https://www.scca.com/pages/find-your-fun/ There is also a map somewhere on the site that shows the individual regions that are near you, but I couldn't easily find it.
I suspect the Rally America site may be of some use. https://www.americanrallyassociation.org/

Hope this helps some.
