Camped for 2 nights at Hickory Hill site 21 (HH021). Highly recommend this premium site. Right in the lake, we could watch the sun rise over the lake. Site had full hookups and was pretty level. The first night we had a lot of tornado warnings and the sirens were going off continuously. Fortunately we got nothing but rain and a little hail, as this started right after we arrived and we had no idea where a tornado shelter was - I highly recommend you scope out the shelters first when camping in OK in Mar/April!
