One of the issues of being in a smallish guild is that the that I'll probably never get to the biggest and baddest adventure hotspots which are reserved for the 40-man (old world) and 25-man (Outland) raids. In the past the Ravns have scraped together enough people to go visit select Azeroth raid instances, namely Blackrock Spire, Zul Gurub and AQ20, but the bigger locales - AQ40, Onyxia, Blackwing Lair, Molten Core and Naxramas - were pretty much beyond us.
In Outland, the "big" instances are SerpentShrine Cavern, The Eye, Magethiron's Lair, Gruul's Lair and the Black Temple. These are 25-man locales and thus notionally accessible (though the odds on having that many people online within the guild is pretty slim). More accessible is Karazhan (a 10-man run) and the forthcoming Zul Aman (ditto), and after 2 months of regular trips to Kara we're still barely halfway through so theres some mileage there.
I would, however, like one day to adventure in the larger instances (more than just a "sticking head through front door" which is how the attached photos were aquired), though that may (like ZG and AQ20) rely overmatching the locale after levelling with WotLK comes out.
