I see that Kent have a country membership for those who live over 75 miles from Canterbury. Because I live over 80 miles from Edgbaston, a Warwickshire 75 mile limit would benefit me, though it doesn't seem all that generous.
I recall that there may have been, in the past, not only a country membership but a distant country membership for those living a really long distance away.
Reading Leslie Duckworth's Club history, I see that in 1972, the country membership limit was just 15 miles and a proposal to increase it to 20 miles was defeated. The ordinary membership rate was increased to £7 (!).
Going back still further, Duckworth reveals that in 1959, membership rates had gone up from £2 2s (two pounds and two old shillings) for ordinary members to £3 3s; and for country members from £1 10s to £2 2s. It was pointed out at the members' meeting that members had free admission to Test matches (yes, really!).
I also read with some amusement that, in the debate, there were those arguing for more use of out-grounds!
