I went to the Puyallup fair last week also. Went during the $2 ride day which made it a bit cheaper than normal. I wanted to ride the coasters, specifically Kersplash which I had never ridden which is up for sale right now, so although the dirty water in it put me off before I was going to ride it this time. We rode the wood coaster 3 times and all were good. I didnt get last seat on first two rides and was starting to worry the re-build took away a little airtime, but when I rode the last seat on my 3rd ride it clearly is still all there, what a great little coaster, to bad it was open a bit more than twice a year! Then we rode the Wildcat, a fun coaster that has a fairly run down appearence now. Then we went to Kersplash, we watched a few riders and could see you would get a bit wet but not to bad, the water in this thing always looks like a sewer so I have avoided this one for years. Anyway, I have to say I was surprised how fun a ride it is, nice swooping drops, Miler makes some decent coasters, I rode the little kiddie coaster made by Miler at Oaks Parks in Portland made by Miler and would say that may be the best kiddie coaster I have ridden.
We wanted to ride the Mouse but as previously stated, they dont let you ride alone, and last time my son and I rode together it was cramped as hell. I am 6' and hes 6'5" so we just cant fit in it. I dont get why single riders cant go on this. We rode a few flat rides, got some fried clams and then took off. This fair/park has more rides and better coasters than the nearby 6 Flags Wild Waves if you ask me.
