When participants dive off the Sternwheeler early Monday morning to take part in the 73rd annual Roy Webster Cross Channel Swim, members of a Gorge amateur radio group will be helping to ensure it all goes safely.

Radio Amateurs of the Gorge — or RAGS — has provided communications services at the cross channel swim for decades. Longtime member and RAGS Cross Channel coordinator Gene Mielke has worked at the event since moving to town in 1984, but believes the group’s history goes back even farther.
