Starting to get nervous

I'm renting a 26 ft truck. My fear (and partially hope) is that 4 times that worth of stuff shows up. Lol. I'm getting paid a flat rate from the host so I'm not worried about nobody showing up. I'll make a decent buck even after expenses. It's not being advertised publicly so that calms my nerves a little. The host is a real estate office and they're sending flyers to employees, friends, family, and clients. So a decent audience, but again, not wide open public. I will definitely be taking lots of pictures so that I can use them to advertise event holding in the future.
