My experience is probably irrelevant for your research as I am in the UK.

No one single day i attend exceeds $500 in GBP equivalent.

Typically i will shoot between 8 and 10 days a season.

Shooting and beating combined i am probably involved in around 20 - 25 shoot days per season.

I also probably spend a total of a week carrying out work on land we shoot over.

My shoot days are generally low cost traditional local and social shoots as apposed to a shoot which is run as a business of the type well represented on youtube and in the sporting media.

What on earth is tower released pheasant shooting? It sounds like an abomination I am imagining guys throwing birds from a high tower?
