Indeed I did do one in April, and my NEXT one is 3 weeks from tomorrow. It was a great challenge, a TON of fun, and so rewarding. Honestly, it was a BLAST! Not easy, but not impossible and the teamwork and satisfaction from everybody working together was incredible. As long as you can handle the distance, the obstacles will be fine.
HAVE A GREAT TIME, and be sure to wear stuff you don't mind getting dirty (although I was able to wash mine clean, but some stuff CAN get ripped up or shredded/ruined).
