Often times land owners stay in the Happy Camp campground on the weekends and bring their boats for little "mini vacations". You'll also have the ability vote in the community elections and have the ability to get involved in commitees or clubs that interest you.
As a land owner, there are no rules about when you have to build your home - you can choose to keep the empty lot as long as you like and continue enjoying the amenities.
Congrats on your decision to purchase. Hopefully, we'll see you around the lake soon.
