Summer's here, and you want to spend your weekend burning steaks somewhere other than your backyard. Meat In A Park lets you find nearby public BBQ locations and promote your own BBQ plans via Facebook.
Enter your address and the site pops up a map showing nearby BBQs (within a 20km radius) and listing their facilities. The coverage is far from nationwide -- most of the data comes from local council sites -- but it's a good start, and you can add details of your own favourite BBQ locations. The site uses Facebook Connect, so you don't need a separate account. For another leisurely maps approach, check out Playground Finder.
