arena footing

["Nancy Cox" <ncox@bendnet.com>]

We have just built an indoor arena 60 x 108.  Our natural soil is sandy dirt
and lava rock.  We are planning to put something in for better footing and
to cut the dust, any suggestions of what has worked for you.  We want to
research this before we put something in that won't work out very well.

Thanks.
