Have an envelope from Keith's Key o' the North from June 1958. Was on Lake Kaubachien, Hazelhurst, Wiconsin. Rates were $85 each for living room, bedroom, double bed and private bath, three meals a day, served in your cottage if you wished (at no additional charge), use of a rowboat and a sailboat at no charge. Water skiing was $4. Our bill for the week was $181.16. Had three beverages at $.70 each, gas $1.00 and stamps $.06. What a wonderful trip! There is no specific address listed on the lake.
