Dominion Brook Park is well worth a visit; make sure you go for a walk along the brook itself where it runs along the far right (south) side of the park.
A) The posted co-ords will take you to an info sign and a Welcome sign. On the Welcome sign you will find the last number of the year the "park dates back to" = A .
B) On the same sign find the 4th # in the phone # and add the number of flowers on the Welcome sign. = B
C) At stage 2 (48 37.346 123 24.909) change Eugene's middle initial to a number. = C
D) Stage 3 (48 37.358 123 24.940) will take you to Sam's lovely garden. Have a wander about and then find the last number of Sam's birth year. = D
E) Also at stage 3, the 3rd number of Sam's birth year = E
F) At stage 4 (48 37.343 123 24.986) sit a minute and keep little Julia company. The last letter of her brother's name gives you F
G) At the same bench, the last letter of her sister's name gives you G
H) Stage 5 (48 37.359 123 25.041) takes you to one of the many magnioficent trees in the park. The last number of the date on Christine's plaque = H
I) Stage 6 (48 37.362 123 25.055) is another bench. Count the number of "Ps" on the plaque. That = I
J) Now go to stage 7 (48 37.334 123 25.058)2 metres behind the benches is a large fir, that has a small metal tag. The sum of the second and third numbers on the tag = J
The final hide is an easy walk away, although not in the park. It is at N 48 A B . C D E W 123 F G . H I J
