O keszu:

W miarę proste, trzy etapowe multi.
Na etapie pierwszym stoisz przed budynkiem, koło wejścia do którego wmurowano tablicę poświęcona Modestowi Sękowskiemu. Jedna z linii tekstu zapisana jest w alfabecie Braille'a. Która (liczymy od góry)? Jej numer zapisz jako AB.

Udaj się na etap drugi (waypoint: wawóz / gully) - stoisz w wąwozie nazwanym imieniem Modesta Sękowskiego. Stojąc na współrzędnych po swojej lewej stronie masz latarnię. Jest na niej dwucyfrowy numer. Zapisz go jako CD.

Teraz masz wszystko, co potrzebne jest Ci do dotarcia do finału.
Zebrane liczby podstaw do wzoru (nawiasów nie mnożymy!)

N 51 (D-B)(A+D).(B-A)(C-D)B
E 22 B(B-A).A(C-B)(C-B-D)

W keszu znajduje się logbook i ołówek. Zamaskuj tak, jak było.

Z racji tego, że kesz znajduje się w terenie dość mocno zabudowanym, do tego pofałdowanym i porośniętym drzewami, to sygnał może pływać. Koordynaty z dokładnością do 7 metrów.

Modest Sękowski (1920 - 1952) lost his sight as a young boy, in a result of failed chemical experiment. Till the end of his life he as only able to tell light and dark apart.

After Second World War he came to Lublin - he studied at Lublin Catholic University and here he co-founded Lublin Cooperative of the Blind, very first in Poland. In the peak of its operation, the Cooperative had 700 employees, while currently there are 200 people employed there.

Modest Sękowski also organized Lublin branch of Blind Employees Association (which later become Polish Blind Association) and other cooperatives for disabled and visually impaired.

Currently, Modest Sękowski is parton of Lublin Cooperative for the Blind as well as parton of a gully located in Lublin district of Wieniawa.

About the cache:

Fairly simple, three stage multi.

At stage one you're in the front of the building. Next to the entrance there's a memorial plaque dedicated to Modest Sękowski. One of the lines is written using Braille alphabet. Which one? Write down its number as AB.

At stage two (waypoint: wawóz / gully), you're in the gully named after Modest Sękowski. On your left hand there is a lamp post with a two digit number on it. Write it down as CD.

Now you've got everything you need to get to the final. Put the collected numbers in the formula (do not multiply the brackets!)

N 51 (D-B)(A+D).(B-A)(C-D)B
E 22 B(B-A).A(C-B)(C-B-D)

Cache contains a pencil an a logbook. Mask the cache as you found it.

Since the cache is placed in vicinity of gully, high trees and large number of buildings, the coordinates are with accuracy of about 7 meters.
