the feeling of utter depression and exaustion after attending an overnight USY event that you will litteraly fall asleep on anyone.
the freshman had such a USY Hangover after R.C. that she fell asleep on a senior while her pillow pet was being passed around the room.

The best Jewish summer program you will ever attend. Whether it's traveling cross country, Israel, east, west, or cruising to Alaska. USY on wheels will create memories and friendships that last a lifetime. Singing Ruach, Shabbat shopping, and night time bonding activities are just a few of the amazing experiences USY on wheels has to offer.
