As for me, I can't do the 14th or 15th.
If you want to ramrod a get together, I'd suggest just do it! Pick a date, pick a place, grab a mini grill, a package of brats and extend an open invitation. If someone wants to join in on the fun, bring a food item to share, something to drink, a chair and join the fun. Oh, Please somebody bring a trash bag or two, thanks. You may be surprised at the turnout. (the fishing is just an excuse to get together)
