Original poster's note: I got this recipe from my mother-in-law, she has used it for 30 years and I will probably use it for 30 more!
List of Ingredients
2 quarts thin sliced cucumbers
2 sliced onions
2 tbl. salt
1 cup white vinegar
3/4 cup sugar
Recipe
1. Mix Cucumbers and Onions together and sprinkle with salt, mix well and let stand 2-3 hours.
2. Rinse and drain well.
3. Mix Vinegar and Sugar till sugar is disolved.
4. Put cucumbers and onions in freezer containers or freezer bags, pour vinegar/sugar mixture over cukes and onions (I only fill mine half full to leave room for expansion during freezing).
5. Freeze 3 weeks before eating, the longer you let them sit the sweeter the pickles.
6. Thaw in refridgerator or in cold water.
