I've made several of these, mostly the ones listed in the first 10 recipes.  For #4 (the broccoli salad) I skipped the raisins and added small red grapes instead.  Besides potato salad, the other one I make almost all summer long is the cucumbers in sour cream sauce with dill.  I do not add sugar to mine as some do, and if I can find it I add fresh dill instead of the dried herb.  My friend gave me a whole bunch of baby cukes yesterday so today I'm making more cukes 'n dill to go with our hobo dinners for supper.  It's been raining like crazy here and it's been fairly cool for the past couple of days, too, so hobo dinners sounded like a good idea.  We've had more rain this summer than I can remember in the 30 years we've lived here - it's been just incredibly wet.  I found silverfish in the lower level in my laundry room - ewwww, I hate those things.

Anyway, here's the list of salad ideas:
