I got so lost both coming to L-burg and leaving...I'm glad I have a decent sense of direction because I only had an image in my head of the directions I got off google maps and didn't think to remember other road names etc.
In the AM, I missed Hill Creek off of 15501 and got almost to 74 before realizing I must have gone to far. So I head back north on 15501 and go another 15 miles and decide just to make a right on one of the roads that say Wagram. So I do so and follow signs and eventually hit a stop for main street. I go left and I see this Shell station with a dirty, stickered up Integra R....bingo I made it!

.
Leaving, I forgot to turn right at Riverton so I stayed on Airbase road so I whittle my way back to the Shell station in similar route to what I did in the morning. Got on Hill Creek finally. Drove on that for a while and got to a funky intersection with N. Turnpike and I didn't know if I got straight or not, so I turned left on N Turnpike and eventually got to 15501 N.....only about 8 miles SOUTH of where I was. Anyway, I eventually pass Hill Creeks intersection with 15/501 and I did not see a Pine Lake RV sign. But I did see a horse crossing sign and noted that if you go by the golf pro shop, you passed.
Hopefully it'll be easier next time

I'll second Steve in saying that Mapquest and Google maps both said coming from Durham to L-burg was going to be 2.5-2.75 hours but had I not got lost, it would have been a hair over 2 hours and I don't drive particularly fast (5 over at most).
