punomatic, we stayed a week there several years ago. We were in Helena the year before and drove thru Garrison and saw the park, took a ride thru, grassy, looked fairly good. As fulltimers we usually do no less than a week at a park. So the next season we pulled in off I-90 and took a week. There were some sites in the rear which looked OK. They put us out toward I-90 which was fine with us. Well some things raised their ugly head. First of all the sites were side-by-side, I park one way, you come in and park the opposite direction. Use the same power ped. etc. And they park you. My drivers side slide was going to be the near the ped so I got out my "slide stick" to make sure it would work. It would, but on the door side of the RV there was all sorts of room over to the next guy that even had his awning out. After the guy pulled into the spot beside us and he pushed his slide out, we could have passed a ham sandwich to each other thru the window. The first couple of days it was cool and no power problems. But then the temps went up and as RVers would pull in during the afternoon, fire up their AC the power dumped. We have a electric management system on our fiver, it kicked out due to below 107 volts. Shortly after, it kicked back on but for only about a minute. There was a motor home at the end of our row. I had noticed he had the same unit we do but it was portable on the ped. I saw him standing outside looking, so I walked down and asked him if his power dumped. "Yep", he said, "every afternoon it heats up and folks start coming in off the road". We later did laundry, my wife kept having to dump quarters in the dryer, it wasn't heating well due to the lack of power. Later that evening I was standing outside and a guy comes up and asks how I was doing. I said good but if the power would stay on, I'd be great. He said "I'm the owner and yes that is a problem but the power company won't sell me more power! I sure didn't jump off the turnip truck yesterday. Then we found out that if you pay by the day you pay extra for 50 amp. Since we paid a week the charge was the same as 30. Of course we haven't been back but have passed several times. Now I can't say if it is the same owner or not so it is "buyer beware"!
