@ MapNerd looks cool so far. This would be a great tool particularly if there were reports on a number of parks near each other. Depending on my objectives it might sway my decision on where to stay.
Seems like I've experienced considerable speed measurement differences between Ookla (typically what I use) and Fast.com.
Would it be appropriate to either include what speed test was used or perhaps encourage all contributors to use a particular test site just to keep the results apples to apples. .....ops I, meant pineapples s to pineapples...
It might also be good if the contributors would report (briefly) their set up. i.e hotspot only, external antenna, Cell booster etc. Maybe a set of check boxes could cover the basics and those with more elaborate routers, modems, antenna, etc. could provide a free style input.
