I HATE SUMMER!!!!! grrrr. sides collapsed on me twice, first time i had enough time to fix, secoond, it collapsed in transport. lucky it was just for my lil sis so she was still very happy with it, we just put the yuck at the back..=( so angry, held up fine for a whole day and night in crumb coating process.. then just when i thought i had finished.. BAM! dam heat!!!! thats all i can put it down to.. it had a great angle and supports.. etc. anyone else know what may have caused this???
