Anyone can get soaked at any time.
Even wearing a poncho might not save you.
If you let the poncho move off of your leg, your leg might get soaked.
If you don't wear the hood b/c you feel like a goober with it on, you might get soaked even down into your shirt, because the water might splash DOWN on you.
Even if you have your hood on, if you're sitting just right, or rather wrong, the water coming down might go down your ponch front and into your v-neck shirt. Brr.
You might not have a poncho on and NOT get even a drop on you!
You might not have a poncho and not get a drop for the first four times you go on it, then the 5th time, drench-o-rama.
It's a super-fun ride we love it.
I went with DH and DS 4 times in a row on the first day, wearing a poncho while they did not, and got semi-wet. They were relatively soggy. Then they went again. BWA HA HA HA got drenched. Luckily I was prepared and it was our last ride before a break anyway. (we went on 5 times in a row the second day too, and we were all drenched b/c DS got cold and wanted my poncho, which I kindly gave)
During the winter months, from our experience, it SEEMS that they don't have the geysers on. But when the geysers are on, ALL bets are off, nothing is for sure, because those geysers CAN get you. It's especially fun when you can hear the geyser come on, you hear and feel it pummeling the bottom of your raft, you THINK you're safe, you get off the geyser and there's just enough water to go UP in the air and whoosh splash down on you....
Oh I love Grizzly. And I love that you're put with other people if your group and their group isn't big enough to fill the boat. It's just too much fun to experience it with people other than your own group!
