Kidsploration!
Just for fun, here's a couple places I've been exploring lately
Victorianna Castle, Hogback
This place is like a fairy tale princess castle, all white marble. I kept expecting to see Cinderella or Belle or some other Disney princess to step out of an alcove. There is a store there, focusing on gothic lolita dresses, but even if that style isn't yours, it's still a super pretty place with lots to explore.
Lake Gnoma
A nice, natural lake and campsite, featuring canoeing and other fun stuff. Worth taking a tour around, especially if you like natural.wildlife environments. Grab the freebie walking stick in the cabin by the lake, too.
Greenies Home Rezzable
One of the bestest builds I've seen in a long long time. This home is built to put you on scale with the "Greenies," tiny aliens created by inworld artist Light Waves. The "house" is huuuuge, an requires a 300m draw distance jes to see across the living room! Not all the items you'll find exploring the house are kid-friendly, but the folks who made the place are. Check out the hamster balls scattered on the floor as well as the hidden trampoline (I'm not gonna spoil it!) in the kids' part of the living room. ALso, make sure to get up to the mother ship from the main hidden teleporters.
EGO Terra
You'll find another giant house here too. Not as huge as the one in Greenies Home, but still a fun place to explore. Of more note are the recreations of cartoon places, You'll find the Simpsons' house and Moe's Tavern, the Animaniacs' water tower, Scrooge McDuck's money bin, the Planet Express Building, and Invader Zim's place. Not a lot other than eye candy - but it's really good eye candy.
Livingtree
Okay, I'm way biased, cuz I helped build it and I have a store there, but check it out. There's a large kids' playground, a bay you can dive around and swim in, a small campsite, a drum circle, free kayak rentals, a Neo-Realms fishing francise, and tons of places to explore. Look for the hidden cave. As mentioned, my store is there, as is my brother Pygar's, and all of RObin Sojourners stores. It's the main place to find her skins and shapes for boys and girls, amongst other stuff.
Have fun exploring!
