Indoor cricket is brilliant. I used to play and work at the indoor centre in Worcester for years before it closed and changed into a bowling centre. Great game, very fast paced and keeps your eye in over the winter and great for your fielding skills. No coincidence that my little village team won their mid week league 3 years in a row while we had a team playing there all winter.
It was very competitive at the top level. I opened the batting with David Leatherdale for my team and regularly played against the likes of Steve Rhodes, Richard Illingworth and other county players. Real shame it closed, miss not playing and way better than just nets. Still some centres about, mostly up north I think.
