We started to look into those car-top carriers and my goodness those things can get expensive! Since we didn't want to spend $500 on a special one, we started to look into used ones but those still were reselling for more then we expected on Craigslist and online community yard sales. We thought maybe we could borrow or rent one from friends but that would be asking too much to take it for 1.5months at the peak travel season/end of summer. So we started to look harder and sure enough Kmart and Sears came through! For $130 we were able to use coupon codes and online coupons (and what I like to call my husbands magical & savvy way to making things cheaper) and sure enough we were able to get a great hard car-top carrier to make our lives easier! I'll let you know if it works well by the time we drive down the East coast, but right now we are happy with the amount of room it provides and seems sturdy enough for our needs too!
