Well, my dad has only just got back
But, already, he has informed me of his next travel dates:
1) May - not good, another free week (holidays) with not much caching.
2) July - not good, Geolympix is on, and start of the summer holidays .
3) September - My birthday, and CacheWalker event is on!
I have begged him to change the dates, and he said he'll try, particularly for September and July as they're further afar.
Fingers crossed - I don't wanna have another caching drought
