I am so incredibly glad and lucky that I had the chance to spend my college years in one the most unique and eclectic cities in the US. If you haven't been there yet, I definitely suggest you go. I can recommend some awesome restaurants, fun places to go to be outside, hole-in-the-wall bars and shops, and special events that you wouldn't know about unless you lived there. My sister even followed in her big sis's footsteps and is now a Longhorn as well.
When the weather gets warm enough, I definitely want to make a trip down there to float the river (if not multiple times). And maybe, even an outing to go on a boat on Lake Travis would be nice. Oh summertime.
