To be a roadie on a B4B trip, it helps if one is a) extroverted & enthusiastic; b) a coffee fiend; c, d, & e) patient; f) friendly; and g) adaptable.
Having never been a support crew member on my previous B4B trips, I was nonetheless aware of the crucial fact that a ride simply cannot happen and function without a solid squad working 'behind the scenes'. Most breakfasts and lunches are provided by the road crew, including some dinners. So every night there are people in the church kitchen prepping the next day's meals, and most mornings the kitchen is alive with our people prepping coffee and breakfast.
We were provided barbecue meals at the Anglican Church in Sydney, and New Life Church in Duncan, and terrific hot meals in the other towns. Since we were on the west coast, salmon was on the menu more often than not, and always done to perfection!
Obviously there is more to hosting a large group overnight than just providing meals. Often, the host church provides volunteers to help drive everyone to the local rec centre to clean up, and the usual tasks of opening and closing the building, providing space, making sure the kitchen is fine for us to use in the mornings. Sometimes there are people within these congregations who make it their ministry to provide a meal for the groups that come through their area. They do so with incredible enthusiasm and friendliness, and you can tell that this is important to them.
One of my mottos when I go fishing is 'the more the merrier!' (i.e. more fish to eat!). And the same can be said for roadies on a B4B ride. Things generally go much smoother with more support crew, and besides, I think the cyclists are always happy to see a friendly face with a big smile encouraging them during the day, especially on tough long, hot or wet days.
