The venues that show no sense of reason with teaching beginners deserve to see a decline . They certainly won’t endear themselves and it is short sighted . If you are situated in the West Midlands , then you absolutely must join the Bham anglers assosiation ! For 50£ approx you and your grandson can go for 1 hour or all day , Every day of the week .! :p . Even your local canal could be a good option ! His first fish may be a tiny perch . Even so he will either get the bug or perhaps not . Visit every tackle shop in your area and most will be very helpfull with your requirements . Explain that you’re not a member of the golfing fraternity with a money tree at the bottom of your garden . There are usually clubs and syndicates in most counties that cater more for youngsters and beginners alike . Spend more time and effort doing the homework and bring him on with the RIGHT kind of fishing . You will save lots of money to spend on petrol and tackle and bait . Best wishes 🙂 🙂 🙂
