In Gridland, the cities are arranged in a 4 by 6 grid:

A-B-C-D-E-F
| | | | | |
G-H-I-J-K-L
| | | | | |
M-N-O-P-Q-R
| | | | | |
S-T-U-V-W-X

A man born in A (and never ventured outside his city) has to visit a man in X but wants to take a detour to get there. He wants to visit every city but not enter any city more than once during his tour. How should his trip go?

I'm assuming he lives in A, needs to visit in X, then go back home (A).......

A - G - H - I - O - N - M - S - T - U - V - W - X - R - Q - P - J - K - L - F - E - D - C - B - A

or just...

A - G - H - N - M - S - T - U - V - W - X - R - Q - P - O - I - J - K - L - F - E - D - C - B - A
