Bald Ridge Campground and Old Federal are wonderful COE campgrounds on Lake Lanier and not that far from Helen and Tallulah. We spend time at both of them every year even though we live fairly close by in northeast GA.
I make a plain white sauce, pepper but no salt because of the salty beef - always keep several jars in pantry. We like it served over Chinese rice noodles so we have some crunch along with the soft sauce.
Vogel State Park is the best for this family - this has been our favorite for many decades. We have traveled extensively in our motorhome, but pulling into Vogel is like 'going home'. A beautiful park, great staff, things to do for every age. Note: And we live in Dahlonega, which is the site of the first major gold rush in our country; only about 25 miles over the mountain from Vogel.
