Ann,
It depends on the preserve. There are 100 arce preserves which are far from a hunting experience and there are 600-1100 acre preserves in the Noertheastern U.S. These I feel offer a reasonable duplication of a hunting experience.
It is sometimes the only hunting available to us and if reaserched and done properly you might enjoy it.
I myself think they are great and a worthwhile experience
when time, money and species are not readily available.
Just my humble opinion.
