A 15 minutes car ride from downtown is necessary
to find the final cache location.

The Grant House
Dr Grant, a graduate of Queen’s and McGill universities, also
served as president of the Canadian Medical Association in 1872-73
and of the Royal Society of Canada in 1902-03. He was known to
display eccentric behaviour at times: he apparently entertained
guests one evening by dissecting a human brain to satisfy their
intellectual hunger. He died in his home in 1920, a month after
being bedridden due to a hip fracture.
The University Club used his house from 1920 until 1969. In 1972
Friday’s Roast Beef House opened. Restaurant staff have told tales
of having trays knocked out of their hands when no one else was
present, of hearing their names called from empty rooms on an upper
floor. They tell of a noise, a heavy breathing, that is believed to
be that of Grant because it sounds like a person wheezing, with an
occasional cough. There are also tales that laughter emanates from
one of the back rooms when no one is there. At the posted
coordinates, you will find a plaque on the building.

The Lisgar Collegiate.
The Gothic Revival limestine building house Ottawa’s first
collegiate institute. Its design was not suited for winter cold,
snowy Ottawa winters. The ice built up often on the edge of the
roof with thick sheets of ice. One day in 1941 or 1942 there was an
accident. The janitor was leaning over the edge of the roof to
remove the ice. It is said he slipped on the slicked surface and
fell to his death.
Now, only a few people venture in the maze of pipes and heating
equipment on the fourth floor of the Lisgar collegiate. They feel
that someone is looking at them.

The cache is at N45 DC.DBC W75 BA.AAB
The digital root of the cache coordinate is 7. The cache
location is close to a trail that you can also use to find another
cache of mine; Halloween 2005:The Blair Road Witch. It is a 15
minutes car ride from downtown. I installed a few reflectors if you
dare to go there at night.
