what vegetables should i plant in july?

my vegetable garden is in shambles...again. it has been the second driest july since records have been kept. i missed two weekends of maintanance: the bugs ate the potatoes to skeletal form; i guess the actual potatoes dried up due to lack of water; the deer ate the 'bright lights' swiss chard; the onions and leeks look ok, but they are ensconced in weeds; i had mulched the tomatoes, so no weeds, but the deer trimmed all their new growth; i cant find my sweet potatoes. one surprise, though: i have two very large 'moon and stars' heirloom watermelons! the mister wants to abandon the whole project. i have done this too long, however, and am unwilling to give up! so...i am going to try and salvage this growing season by planting some fall crops right now: i have a whole box of unused seeds. i need some help and inspiration, though. found some on youtube (of course!) via gardengirltv. she has some great ideas and makes it sound do-able. back to the field!
