May I, through the good services of your forum, thank most sincerely Mario McTavish (his caching tag) for giving up this morning to show me the ropes, go through the elements of operating the Garmin and taking me to two nearby caches.
There must be many techno-nervous types like me whose eyes glaze over when confronted with a 'users manual' and much prefer to learn by seeing and doing.
Mario has well over 2000 finds under his belt and has found at least one cache every day for almost a year. His enthusiasm for geocaching is evident and while I fall a long way short of his appetite for the activity (at present) I would not be in a position to go out independently with confidence without the help and support I received today.
Thank you, Mario.
