I've posted some camground reports to the Family Camping section not realizing this section existed (sound of open palm slapping against forehead)! D'oh!
Rather than duplicate those posts here and spending all day doing so may I instead refer you to the Campground Reports page on my blog? The last two campgrounds I reported on both offered free camping: one for a night including water and electricity (and maybe sewer), the other 14 days of ree camping (no hookups). They are Hendrum Community Park and McClure Campground, repsectively.
Besides campground reports my blog has product user reports, photo tips, great photography and interviews with people I have met during my nationwide RV trip of which I'm in my 5th month now.
The add link feature of this site isn't working for me right now so here is the direct URL to my blog. It's free, of course and if you subscribe there you'll get email notifications when something new is posted to the main page. Please copy and paste it into your browser. Thanks.
