The lack of ball movement is what makes it hard. You get very few chances. Thus it's a cerebral exercise as well as a physical exercise and .. I don't know. I find there's a certain finesse to it that is lacking in raquetball. Don't get me wrong, I used to prefer raquetball myself but I have since graduated up in the world
I play at the Southland Leisure Centre. There are a few places closer to me (SLC is not far though), but they're hella expensive. I just ran into Nate at the SLC as a matter of fact and HE was off to a squash game too

So I might challenge him to a game... I'm going to get this Canreef squash ladder going yet. (Brad, it will just take you longer due to the geographic impediments

)
There's a lot more transference, IMO, between badminton and squash than there is badminston and raquetball. I've known a few badminton players who were very good at their game but never played squash, but took to squash right away.
