The final in the series and as family should be: Close-knit and at ease with each other. Hence, the location has been chosen so that the parents protect their children (ps. I was told to keep this one mild as my intentions were to make it much much more inacessible and really wear out some boot soles) and Dad can also keep an eye on some of his EarthCaches. The family unit is composed of 4 persons and two cats; Natacha and Rex.
The series started with:
1 - A cache do Roger [Orion's Belt]
2- Duarte's cache [Alpha Centauri]
3- Mother's Cache [Milky Way]
Dad is a geologist by profession and has studied hard to get his degrees and now uses that knowledge in exploration-based projects to find new mineral occurrences both here and abroad and to feed his family. This keeps him very busy but also opens up lots of opportunities for him to create earthcaches in Portugal and neighbouring countries.
Dad is also a part-time geocacher and started this activity in 2004 with a few caches spread over the country which, much to the dismay of some, most of his caches have prefixes and suffixes and their names don't fit on most GPSr screens but since we're not all perfect...... . At the gentle prodding by fellow coleague Paulo Henriques a whirlwind run for caches started and the LunchTime Gang was sort of formed. This partnership led to the first personal geocoin in Portugal and the rest is sort of history.
People's lives change, their availability, their spirit wanes and waxes and who knows where this will stop. In the meantime enjoy, or not, the Sintra Mountains who, as one wise geocacher has already said, could be divided into 160 m cells and have a cache in each cell.
