Tempted!

I went to Belfast to the camera shop to pick up a pre-ordered new camera rucksack type bag. One to hold my laptop & gear for our long awaited safari (on the 4th attmpt!).
When there, I noticed a 2nd hand 100 - 400 mm lens, I was tempted, but realise I cannot fit it in, even to the new bag, as hand luggage is restricted. I bet I will regret it.
The blip is of the "balls on the falls" in the distance you can see as you enter Belfast from the M1& an advert on the lorry for our local well known crisps, taken using the lens I resisted buying!
