Under adverse weather conditions of frigid, chilling blasts, which would have discouraged any but a heroic band of trail blazing pioneers, the Horace Dey Lentz Highway, Mauch Chunk to White Bear, was formally dedicated at 1:30 p.m. today. Mr. Lentz, in whose honor the road was named, participated. A motor parade led by Chief of Police Frank McGinley proceeded from Mauch Chunk to White Bear and then back to Mauch Chunk.
