Hi there my name is Edgar, I'm 25 and I'm from the states as well (California). I'm definitely looking to do a trip out to Europe around July for about 30 days before i become a slave to graduate school.
It would be great to have some company along for the adventure, thus joining a group of people would be the best case scenario. The one thing i definitely plan on doing is making a stop to Spain early in July to check off Running of the Bulls from my bucket list.
Let me know if your group could use one more, i haven't started planning much other than narrowing it down to the summer.
