It was a hot and dusty day in 1883. The wagon
of the Morgan McGee family was exhausted and
hungry. As they pass along the wagon trail, they
see piles of people's lives that have been
tossed to the wayside - items left in the dusty
path to lighten the load for the struggling
horses.
The McGee family began rifling through the
heap, hoping to find something that would help
them in their own journey. Among the strewn
chests and luggage, pots and pans, blankets
and china, nothing was helpful.
Little Johnny, however, found what looked to
be an ornate chest with a strange wooden lock
on it. The lock had 3 different gears. He pulled
and tugged, but it just wouldn't budge. In his
desperation and haste, he grabbed a stone and
hit the lock, fracturing a gear. Now will the
McGee family ever be able to open the chest
and see inside? Help these pioneers solve the
mysterious lock.
