Reading the replies makes me cringe on how much I spend a year on travel to shoots having just worked it out to be nearly £400 on ferry fares alone [ 7 Winter league shoots 4 GP and Iceni open] then fuel at a conservative 45mpg another £200+. Logically ignoring the fuel side of the transport
I do a bit of photography using a new camera I brought 6 years ago which cost me the price of a Ripley without a stock back then. Then add the various decent lenses.
Seafishing (beach) a quick look in the garage and I must have spent nearly £1500 on rods, reel etc and when I did a lot over the winter months £20 on bait a weekend (usually with a few pout on the receiving end
Computing well I do not fancy even going there but £3k+ over 10 years sounds about right upgrading every 3 years or so and getting very little back.
So after a relative large outlay I think FT shooting is probably the cheapest of my hobbies over the time.
