ok. i did it. whew!
'all day' turned out to be not as bad as it sounded. it was 12 km total, 6 out and 6 back, two breaks each way. the middle two hours was hiking up mt cooke, the highest peak in the darling range in west oz, elevation 582m. whew!
i was definitely the slowest and the feet started draggin quite a bit near the top. i had a rest while the others explored the views from around the peak.
noticed a bit of tingly back partway back but it's fine now. i was DONE by the time we got back out (i really didn't do any practicing up as it turned out...) but it was bee yuuu tee full and i learned 5 local trees. not to bad at all!
that's two mountains down since this trip started!!
and my coz says she considers me to have mastered the knack of left-side-of-the-road driving now (managed, for example, not to hit the wipers instead of the turn signal today on drive #5) and will be able to venture out on my own now. yay!
