I love Baseball; I grew up playing it; watching the Orioles live and rooting for the Pirates/Twins on TV and now I'm an upset Cubs fan; I've been to 18 MLB parks and 4 different minor league parks; as far as Cashmen field is concerned they are the top of minor league parks I've attended and even beat out a few of the Major league parks;
As far as the 51s are concerned, well they are the Blue Jays affiliate so you can't expect too much from them but go figure they were in first place most of the season this year (I had seasons tickets thank you Shari) and got to see many of the games.
The fan interaction is high, they are there to watch the game; participate in the between inning activities and for the most part don't get up and ask you to move during the live action on the field (there is always one person though)
The misters aren't always on behind the back stop and there is a sign saying they only turn them on during low humidity events; I have to wonder when is it not a low humidity event in Las Vegas? Maybe during the one or two weeks we get rain but otherwise they should be on every day. But I digress;
The hidden gem is the club house upstairs; the general admission ticket prices gets you into it; there you can watch the game from an AC skybox; get there early buy the buffet and find a seat with a view it will blow you away to watch a game in a comfortable temp.
