What helps to make finding and choosing somewhere easier? ( Fishing buddies, social media posts, magazines, online permit availability? )
A heady combination of all the above, with the addition of curiosity - the unknown is always appealing.
Very often these days, I have a technique or tackle that I particularly want to use and will tailor a day to match the tackle - which often makes choosing the water to fish straightforward.
And what helps to make the day more enjoyable once you get there? ( Clear beat maps, off road parking, bank maintenance? )
Depends. These days, since the spread of my 'wading ballast' I do like to have the car parking nearby to the fishing. When paying higher amounts for a days fishing, where beats are managed more actively, then I expect the paths to be clear and well kept. Bank maintenance isn't a huge thing for me unless I'm fishing Salmon beats where well-maintained banks are kind of expected/necessary - not expecting a garden, but I do expect some work to have been done.
Beat maps are handy, signs by pools even better.
