As mentioned previously here and/or on Twitter, I've taken to going to places in Second Life either via TARDIS or hoverboard over teleporting or by Stargate. The folks at New London have given me my own TARDIS landing spot on a moon just a ways from a Judoon ship. I've mastered three different routes from The Starship Diner to TMA Nessus and the railyards of Gluphasia. I've easily navigated from Purple in Sansara across the water to Heterocera up the Atoll coast to Starship Diner.
What fascinates me the most is the roadside content. Think of it: about two-and a half years ago most of Mainland was cluttered with cheesy porn and adfarms along bare roadbeds. Now the porn is gone, the adfarms are 90% clear, and the roads paved. In fact it seems properties along these roads live up to what the Moles have put down. There is true inspiration at work.
While I've made the excursion from Cartoon World in Bay City to Abbotts Aerodrome, it's a dodgy route which involves skirting the Ahern Welcome Area to avoid the lag and 4-way region crossing (especially since once you crash, the ride is over; there are no rezzing zones nearby) and traversing terrain there's the risk of hitting a banline.
I've even attempted from Heterocera to Bay City, a very difficult and irritating route by virtue of poor terraforming and intermittent patches of road. Even went from Andrew Linden's office hour location in Denby to Abbotts, an equally unpleasant feat with the added obstacle of a full help island region bordered by banlined parcels.
Sansara needs a major replanning. No access to key areas from roads - when there IS a road - except between the Bay City- Nova Albion - Suburbs sector (and guess what? Two of those communities are not recognized by LL as part of Sansara). You can see they plopped down some regions, added more regions, still more, pieces added here, some snowy ones there, some beach terrain in the corner...
There's no budget for it nor staff. It seems to me many people who once owned estates - when they stay in SL - could be embracing large chunks of Mainland more and more; the dollar auctions are empty.
We're certainly seeing less 512's on Mainland. Homesteads are bringing people into the Noob Continent as a first step (when inhabitants aren't Oldbies or estate owners). They break out from there in search of open spaces and roomy, configurable land. It could be why roadside lands more and more have that fresh look to them. Michael Linden has indicated that he and the Moles have been assigned to add more land to the N C so there's certainly fresh meat for a new generation of property owners to set the look.
