I think a better idea is to have the service. Then announce there will be NO PROCESSION to the cemetary.
Everyone who wants to will meet at the cemetary at XX:00 o’clock for graveside services. And please take your time and obey all traffic laws en route to the cemetary.
Or perhaps a “Bereavement Bus”?
One of the nice things about America is that if you wish to do such for a funeral of one your deaceased loved ones you can.
Well, at least America used to be that way. More and more the Nanny-staters wish to impose their will on the rest of us. Especially it seems when a time honored tradition of repsect and honor is on the line. (Like putting up a cross in memory of deceased soldiers and such...)
That would add a bit of stress to those who attend from out of town. After riding in several processions of our fallen troops it is a comfort to see those who come outside and give respect to the fallen during the entire procession. Most of the families have also voiced that it gave them comfort to see community support during the trip from the funeral to the final resting place.
