As reported in various places, there is a Hot Wheels event this weekend on June 16 at Target stores. It's part of their 50th annivesary celebration promotions.
Based on what I've seen at my local Target, things will kick off Saturday, June 16th at 10am. What that includes it doesn't really say...and it'll probably vary between Target stores. I'm guessing it will be (and should be) geared towards kids. That'll probably mean sales or cars (or a free one!) along with track racing and other family-friendly activities.
I don't know how long the fun will last at Target. If you don't get there at 10a, I don't know what you'll miss out on, if anything. I'd like to think it'll run at least an hour or so...
I'm planning on taking my kid to check it out. Not sure what we'll get out of it, if anything, but it's something to do on a Saturday morning, which is something I can never have enough of.
If you manage to get to Target on Saturday, be sure to come back and share your experience. I think we'll all be interested to see how it varies between stores and states.
UPDATE: Official info from Target. A free car for kids and 10% off.
