Planning Field Day visits based on the ARRL Field Day Locator sites, here's the plan for Saturday visits.
https://goo.gl/maps/NGwno gives you the map with the day starting and ending in Altus. As one can see, just the drive alone is 10 hours, not counting stops. Therefore, this is extremely subject to change.
Using 146.52 and 446.000 for radio, one can also message KC5FM-9 and follow the progress at http://aprs.fi/#!mt=roadmap&z=11&call=a%2FKC5FM-9&timerange=3600&tail=3600
Don't expect a APRS message while driving, however. :)
One might check into the Echolink/IRLP 7203 on Echolink and 9219 on IRLP. There may be activity from WX5EM on http://www.remotehams.com
The Field Day Locator is club sites considered for visits. If contact is to be made, it will be a phone call to the number listed there.
