I have been planning for this this trip for some time, but expenses are higher than expected. It's my fault, not anticipating things like required medical exams, lab work and dental work costs, which are way above and beyond what I thought would be required. 12 lead EKG, exotic blood work tests, full mouth xrays etc. etc. This ate into project savings to the point where I need to raise funds for things like redundant camera gear, heavy clothing, and computer backup hardware.
It's a fantastic opportunity, but the hidden costs are making it a challenge financially.
