You'll have so many of them they will take over your kitchen counter space, fridge, and make your friends and neighbors run and hide when they see you coming with yet another bag of cucumbers to give them. When it gets to that point, you'll realize it isn't at all feasible.
Pears on the other hand are pretty nice. Make sure you get a variety that suits the type of cooking/eating you'll be doing. Some varieties are cooking pears and other eating pears. Trying to eat a cooking pear right off the tree results in disappointment.
Here's pics of my last batch of cucumbers. I had like 600lbs of them that season. Never again.
