Well, to be honest i think we'll be gone all day we leave at 9:30 sharp from Calvery Chapel (addy below) and i dont expect us back until early evening or so.....300 miles at posted speed limit with all the back roads and stuff would be around 8 or 9 hours total, but that doesnt include stops. Its just hard to gauge, i'm sorry. As far as the slow group, this will be the first time this we'll do this so i'm not sure....i don't want to discourage you from coming, but i don't want to mislead you either. I'll try to confirm the two group situation today. 6075 E Livingston Ave Columbus, OH 43232
