Can add to that list....
Ever spent a week packing all your fishing gear, making sure everything is in working order, boxes of flies tied, last minute orders for lines and nets and so on, driven the 4 hours to get to that exclusive loch, booked into the hotel, carted all your gear to the room so you can check it all over for the 10th time, only to realise that your rods are still on the kitchen table!
...Or...managed to get all your work done, so you sneak away a couple of hours early, pull up alongside the river and jump out the car..set your rod up, see a fish rise on the far bank so quickly slip (aye right) into you waders and....realise you had forgotton to but your boots in the car!
....Or...spend several months organising a very special trip to Lake of Menteith to fish in a very exclusive trial, spend days and days sorting flies, turn up, pay the money, load the boat, get to the middle of the Lake, and realise you don't have a rope for your drogue, and spend the day flying past the other boats on the drift.
Yes Mike, it comes to us all...but it adds a little variety to life.
