The league I play in has a mixture of the two; to echo earlier comments, last season's early games on uncovered, damp, low shooters - as an opening bat - was no fun at all (and doesn't do your bat's toe any good with the damp and low bounce!).
Our home pitch is covered and very well maintained - it is a road (many fifties scored there to date), but good bowlers do get something out of it...
All players look forward to home games, for the good facilities and the enjoyment that always follows, win or lose (or tie in an epic game from last season). I joined the club a couple of years ago and I am enjoying my cricket more than ever before...
