We were in 104 and have 108 reserved for the 4th of July weekend. Also have been in 57 and 67. 75 is huge but away from the lake front. Around 67 you won't get satellite unless you have a movable dish due to a stand of trees.
Some of the sites have quite a bit of slope to them, I have to bring extra blocks to level our 41' MH even with all the air out of the front bags and the rear tires on the blocks. Shorter rigs have less problem naturally.
Bass fishing is great, catching them is the problem!! My grandson has a great time there but he sure loses a lot of worms and bobbers. Some good pictures of bass caught there earlier this year in the office.
There was a bass fishing tournament going on the weekend we were there, and a BBQ on Sunday.
Nice, friendly people and the park is well laid out for larger rigs. They don't have their club house built yet but are in the planning stages now.
They've put about 4½ million into it now. One of the financial backers is a member of the same Lodge so I know him personally. (No, I don't get any discounts!!)
Where are you at in Vancouver? We're out in Felida Ridge, near the new Parade of Homes this year.
There's a small tavern/restaurant about 3 miles back toward I-5 on the south side of the road. Good food and fairly reasonable.
We take our seven (7) cats with us, last time there I started working with the youngest to walk on a leash. Causes quit a stir among the other campers when they realize its a cat and not a small dog.
