When I grew up on Yorke Peninsula I didn't really explore it. When its local you tend to think "another day".
I think when you visit a far away place you can try to cram a lot in because you know you are only there for a short time.
It also helps if you do all the easy bits - day walks or no more than 2 nights out prior to last year. There are a lot of long walks I have never done.
And a few tourist locations I have never been - Flinders Is, the North West / Arthur River and North East corners.
But Tasmania is fairly compact and the earlier visits to Tasmania involved driving right around the island - on one occassion we went around it twice.
And always visited for a full month.
There is plenty still to see - on our last visit on the last day we went to St Columba Falls and just happened to poke our nose up a dingy little mountain track.
Before too long we emerged up next to Mt Victoria and ended up walking the Ralph Falls circuit. A complete surprise. We had no idea any of this was there.
As for what I know about - you can blame scrub master for some of that. He does the real bushwalking (like Bobs Knobs & Vanishing Falls) and he used to show us slides from his trips when he was still a South Aussie. But when at Uni I did have the entire South West of Tasmania in 1:100,000 maps carefully arranged on a kitchen wall and would study it intensely. I think that you would call me a dreaming tragic.
I see dee_legg is up late too.
Now for a really easy one (crosses fingers) - but you should click on it to blow it up a bit.
